Answer:

Step-by-step explanation:
We need to find the value of 
Solving:
We know, 


a^0 = 1
so,

So, the value of 
B but I'm not as sure though
The -3 in f(-3) is the X coordinate, so you need to find where the line is on the Y coordinate at that point.
The line is at Y = -9
It is 9 inches because the formula for the area of a circle is πr2 where the r represents the radius of the circle
The pi can be canceled out =
πr2 and 81 π leaving with
R2 and 81
The r2 represents a square number. So square root 81 and you would result in 9 as your answer
