Answer: 
(x) = 
Step-by-step explanation:
f(x) = 9x - 8 , to find the inverse of f(x) , replace f(x) with y , then the equation becomes
y = 9x - 8 , then make x , the subject of the formula ,
9x = y + 8
x = 
Finally , replace x , with (x) and y with x , so we have
(x) =
Volume of sphere: 
, put $r=5 in$
Volume of cylinder:$ \pi r^2 h$, put $r=8 in, \: h=11 in$
Answer:
-2
Step-by-step explanation:
The average rate of change on an interval is ...
average rate of change = (amount of change)/(width of interval)
= (-3 -1)/(1 -(-1)) = -4/2 = -2
The average rate of change between (-1, 1) and (1, -3) is -2.

Answer:
-25 dollars per month
Step-by-step explanation:
It is convenient to compute the rate of change using points where the graph crosses grid intersections. A couple of these are ...
(months, dollars) = (1, 675) and (4, 600)
Using the slope formula, we have ...
m = (y2 -y1)/(x2 -x1)
m = (600 -675)/(4 -1) = -75/3 = -25 . . . . . dollars/month
