The claim is untrue because, in the case of discrete functions, the absence of either function limit does not imply that the limit product of those two functions will also not exist.

When a variable approaches its limit from the right, the function's right-hand limit is the value that approaches. When a variable approaches its limit from the left, the function's left-hand limit is the value that approaches. The limit of a function in mathematics is a key idea in calculus and analysis regarding the behavior of that function close to a specific input. Below are formal definitions that were initially developed in the early 19th century. Informally, a function f gives each input x an output f(x). The limit of a constant multiplied by a function is the same as the limit of the function multiplied by the constant. A product's limit is equal to the product of its limits. A quotient's limit is the same as the quotient of its limits. A constant function's limit is the same as the constant.

Answer:

The answer is B

Step-by-step explanation:

Answer :

D

Step-by-step explanation:

Because when you put it in the calculator it will show if the solution is right. For example,

f(x) = a(x-h)^2 +k

Vertex is (2,-4)

Plug in the vertex and Pick a coordinate to test

I pick (0,-3)

f(x) = a(0-2)^2 -4= -3

Plug in each a to shows that the equation is true . In this case, 0.25 worked!

Answer:

1 Expert Answer When they say f(0) = -5 they mean the point (0, -5) is on the line. When they say f(3) = 4 they mean the point (3, 4) is on the line. In y = mx + b form, we would have f(x) = 3x - 5.

Step-by-step explanation:

The function is to be determined from the given points.

The linear function is [tex]f(x)=-\dfrac{1}{4}x+\dfrac{19}{4}[/tex]

The given values are

[tex]f(-1)=5[/tex]

[tex]f(3)=4[/tex]

The ordered pairs are [tex](-1,5),(3,4)[/tex]

The equation of the line is

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)\\\Rightarrow y-5=\dfrac{4-5}{3-(-1)}(x-(-1))\\\Rightarrow y-5=-\dfrac{1}{4}(x+1)\\\Rightarrow y-5=-\dfrac{1}{4}x-\dfrac{1}{4}\\\Rightarrow y=-\dfrac{1}{4}x-\dfrac{1}{4}+5\\\Rightarrow y=-\dfrac{1}{4}x+\dfrac{19}{4}[/tex]

Answer:

[tex]\mathbf{ f(x+1)=7x-1}[/tex]

Step-by-step explanation:

We need to find f(x+1)

We are given:

[tex]g(x) - f(x) = -2x + 5\:and\:g(x) = 5x -3[/tex]

First we need to find f(x)

By putting value of g(x) into g(x)-f(x)

[tex]g(x) - f(x) = -2x + 5\\\Put\:value\:of\:g(x) = 5x -3\\5x-3-f(x)=-2x+5\\-f(x)=-2x+5-5x+3\\-f(x)=-2x-5x+5+3\\-f(x)=-7x+8\\f(x)=-(-7x+8)\\f(x)=7x-8\\[/tex]

We have, [tex]f(x)=7x-8[/tex]

Now finding f(x+1) by putting x=x+1

[tex]f(x)=7x-8\\Put\:x=x+1\\f(x+1)=7(x+1)-8\\f(x+1)=7x+7-8\\f(x+1)=7x-1[/tex]

So, [tex]\mathbf{ f(x+1)=7x-1}[/tex]

Answer:

[tex]y > 3\cdot x + 5[/tex]

Step-by-step explanation:

Let [tex]A(x,y) = (-2,4)[/tex] and [tex]y = 3\cdot x + 5[/tex]. Now we evaluate the given function at [tex]x = -2[/tex]:

[tex]y = 3\cdot x + 5[/tex] (1)

[tex]y = 3\cdot (-2)+5[/tex]

[tex]y = -6 +5[/tex]

[tex]y = -1[/tex]

Which means that [tex]y[/tex] is less than the y-component of A. Therefore, the right answer is [tex]y > 3\cdot x + 5[/tex].

Total cost of meal is $60

Step-by-step explanation:

The cost of meal = $50

Tip = 20%

We need to find total cost of meal

First find 20% of 50 to get the amount given for tip

[tex]20\% \:of\: 50\\=\frac{20}{100}\times 50\\=10[/tex]

So, tip given is $10

Total cost of meal = 50+10 = $60

So, total cost of meal is $60

In the given question, it will take approximately 2-3 min to climb 1 step taller. It's an estimate of 7.92 hours, if you split 950 to 2, it is the period it would take you to go out in minutes when we turn 475 mins into minutes. As we see it will take them an extra 92 mins for 950 feet to ascend. They can achieve it by ascending this at an average rate of 135.7 ft/h.

Answer:

No, the amount of minutes to climb up 1 foot of the height would be around 2-3 minutes. If you divide 950 with 2, you get 475 which would estimate to 7.92 hours. So as we see they would need an extra 55.2 minutes to climb the full 950 feet.

TT is equal to T-1, so the given matrix is an orthogonal matrix.

What is an orthogonal matrix?

Here, the determinant of T,

 |T| = cos²∅ + sin²∅

      = 1

Now, its cofactors,

[tex]T_{11}[/tex] = cos ∅

[tex]T_{12[/tex] = sin ∅

       [tex]T_{21[/tex]= -sin ∅

[tex]T_{22[/tex] = cos ∅

Step-by-step explanation:

The equation for the given verbal descrption "two and three-fourths times the sum of twelve times a number c and negative seven is equal to thirty-five and three-fourths." is [tex]2\frac{3}{4}[/tex]( 12c -7) = [tex]35 \frac{3}{4}[/tex] and its solution is c = 5/6.

According to the given question.

We have a verbal description for a equation i.e. "two and three-fourths times the sum of twelve times a number c and negative seven is equal to thirty-five and three-fourths."

So, the equation for the above verbal description is given by

[tex]2\frac{3}{4}[/tex]( 12c -7) = [tex]35 \frac{3}{4}[/tex]

Therefore, the solution for the above equation is given by

11/4(12c - 7) = 143/4

⇒ 11(12c - 7) = 143     (multiply both the sides by 4)

⇒ 132c - 77 = 143

⇒ 132c = 143 + 77

⇒ 132c = 220

⇒ c = 220/132

⇒ c = 110/66

⇒ c = 55/66

⇒ c = 5/6

Hence, the equation for the given verbal descrption "two and three-fourths times the sum of twelve times a number c and negative seven is equal to thirty-five and three-fourths." is [tex]2\frac{3}{4}[/tex]( 12c -7) = [tex]35 \frac{3}{4}[/tex] and its solution is c = 5/6.
