Question

What is the inverse of the function f(x)=4x

Answer 1

Here's my original function:


`y = 4x`

Now, I'll try to solve for "x=".


`x = (y)/(4)`

Once I have "x=", I'll switch x and y; the "y=" is the inverse.

Answer 2

f(x) = 4x
y = 4x
x = 4y (divide both sides by 4)
x/4 = y
The inverse of f(x) is x/4
