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
$g(x)=a f(x)=5*2^x$

Crank

Answer:

b ≥ 5,000.

Step-by-step explanation:

1. Use the information given in the problem to write the inequality... such as box tops & the amount of 5,000 box tops.

2. b represents the number of box tops for the fundraiser. Therefore, based on the information provided, the value of b must be greater than or equal to 5,000 box tops. So, you get the inequality is:

b ≥ 5,000

3. Then you graph it, you must use a closed circle for ≥.

~~(the graph is different, but you should be able to understand it.)

The average view of the dress code is that this dress is not good

<h3>Explain how Rashad could collect data to ensure that it is a random sample of the population.</h3>

For Rashad's sample to be a random sample gotten from the population, the following must be considered.

First, he must have a defined population. In this case, his population is all the students in his high school (non students are not to be considered)
Next, he must have a defined sample size (say 10% or 20% of the total number of students in the school)
Next, he must select students at random (a perfect example of this is one of every five or ten students that enters the school gate.
Lastly, he must collect data for his sample

<h3>Create a visual plot of the data in the table by constructing a bar graph.</h3>

To do this, we simply create a bar graph.

The response would go into the x-axis, while the number of people would go into the y-axis

See attachment for bar graph

<h3>What is the average view of the dress code? How did you come to this conclusion?</h3>

The average view of the dress code is that this dress is not good

It is considered the average view of the dress code because it is the opinion with the most frequency
