If f(x)=5x-25 and g(x)=1/5x+5, which expression could be used to verify g(x) is the inverse of f(x)?

a) 1/5(1/5x)+5

b) 1/5(5x-25)+5

c) (1/5x+5)

d) 5(1/5x+5)+5

i got 86 for this

hope this !

if you need an explanation just ask

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

1       7.6

2       7.2

3       6.8
