Answer:

Step-by-step explanation:

It is two types of function.
- Exponential Growth: If function increase as value of x increase.
In this case, a>0 and b>1
- Exponential decay: If function decrease as value of x increase.
In this case, a>0 and 0<b<1
We need to choose exponential growth function.

Here a=0.75>0 and b=5>1
Therefore, This function is exponential growth.
Multiply 120 by 0.40 to get 40%:
120 x 0.40 = 48
So 48 is 40% of 120
X is less than or equal to 3
X is less than 9
X is less than -5
X is greater than or equal to 13
