Answer:
The graph in the attached figure
Step-by-step explanation:
we have a exponential function of the form

where
y ---> is the population of bacteria
x ---> the number of hours
a is the initial value or y-intercept
b is the base of the exponential function
r is the rate of change
b=(1+r)
we have


so

substitute

For x=20 hours
substitute in the equation and solve for y

For question A, the answer is 2. Since the sale sweatshirt if 40% LESS, this means that 60% of the original price still remains. 28.80 x .60 = 17.28
For question B, the answer if 4. You can divide 17 by 20 getting .85
To find the inverse of a function, replace every x in the equation with a y, and replace every y in the equation with an x:

Add 9 to both sides:

Square root both sides to get y by itself:

This equation can be simplified by taking the square root of 9 out of the root:


The inverse of this function is
y = 3 + √x.
