If f(x) = x - 1, which of the following is the inverse of f(x)? a. f-1(x) = x + 1 b. f-1(x) = 1 - x c. f-1(x) = x d. f-1(x) = x - 1

A is the answer.

y=x-1

y+1=x

x is F inverse(x)

F^(-1) (x)= x+1

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y

0       8
