Which represents the inverse of the function f(x) = 4x? h(x) = x + 4 h(x) = x – 4 h(x) = x h(x) = x

Question

Which represents the inverse of the function f(x) = 4x?

h(x) = x + 4

h(x) = x – 4

h(x) = x

h(x) = x

Answer 1

to find the inverse function simply replace "x" by "y", replace "y" by "x", and solve for y

f(x)=4x

y=4x

x=4y

y=x/4 or h(x)=(1/4)x
