Answer:

f(x)=5(2^x)

A is the correct option.

Step-by-step explanation:

We have been given the parent function f(x)=2^x

We have the transformation rule:

Rule: If the parent function y =f(x) is stretched vertically by a factor 'k' then the equation becomes y=kf(x).

Here, the exponential function f(x)=2^x vertically stretched by a factor 5, hence, k = 5.

Therefore, the equation for the new function is

f(x)=5(2^x)

A is the correct option.

A vertical stretch of f(x) by a scale factor of a is 
g(x)=a f(x)

For f(x)=2^x, and a=5
the vertically stretched function is then
g(x)=a f(x)=5*2^x

Mrac [35]

Given:

The faces on a number cube are labeled 1,2,2,3,4, and 5.

The number cube is rolled 114 times.

To find:

How many times would you expect the number 2 to appear?

Solution:

We have,

Total outcomes = 1,2,2,3,4, and 5.

Number of total outcomes = 6

Favorable outcomes = 2 and 2

Number of favorable outcomes = 2

The probability of getting 2 is:

P(2)=\dfrac{\text{Number of favorable outcomes}}{\text{Number of total outcomes}}

P(2)=\dfrac{2}{6}

P(2)=\dfrac{1}{3}

Now, the expected number of times when 2 to appear is:

E(x)=114\times P(2)

E(x)=114\times \dfrac{1}{3}

E(x)=38

Therefore, the expected number of times is 38.
