Question

What is the inverse of f(x)=10^x ?

Answer 1

solve x = 10 ^y

Answer 2

for y

Answer 3

would it be log base 10 of x = y ?

Answer 4

yes, so the inverse function f^-1(x) = log base 10 of x

Answer 5

The inverse function is a reflection of the graph over the line y = x

Answer 6

graph both of those and graph y = x to see this

Answer 7

why is it marking me wrong?

Answer 8

@DanJS

Answer 9

do you have to enter the base somehow?

Answer 10

try to put in log(x) / log(10)

Answer 11

oh yes it worked. thank you!
