A function that represents the exponential function f(x)= 3 to the power of x after a vertical stretch by a factor of 8 and a reflection across the x-axis is
.
<u>Step-by-step explanation:</u>
Here we have to make A function that represents the exponential function f(x)= 3 to the power of x after a vertical stretch by a factor of 8 and a reflection across the x-axis . Let's find out:
We have ,
- A function that represents the exponential function f(x)= 3 to the power of x
Following is the equation for above statement :
⇒ 
- A vertical stretch by a factor of 8
Following is the equation for above statement :
⇒ 
- A reflection across the x-axis
Following is the equation for above statement :
⇒ 
⇒ 
Therefore , A function that represents the exponential function f(x)= 3 to the power of x after a vertical stretch by a factor of 8 and a reflection across the x-axis is

The group rent 11 river rent tubes and 4 cooler tubes.
Step-by-step explanation:
Rent for river rent tube = $20
Rent for cooler tubes = $12.50
Total spent = $270
Total tubes rented = 15
Let,
x be the number of river rent tube.
y be the number of cooler tubes.
According to given statement;
x+y=15 Eqn 1
20x+12.50y=270 Eqn 2
Multiplying Eqn 1 by 20

Subtracting Eqn 2 from Eqn 3

Dividing both sides by 7.5

Putting y=4 in Eqn 1

The group rent 11 river rent tubes and 4 cooler tubes.
