I need help!!!! <br> Which represents the inverse of the function f(x)=4x?

Mrac [35]

Answer:

$h(x)=\frac{1}{4}x$ .

Step-by-step explanation:

The inverse is basically you just swapping x and y. People want to solve it for y to make it a function of x.

$y=4x$

Swap x and y:

$x=4y$

Now solve for y by dividing y on both sides:

$\frac{x}{4}=y$

$\frac{1}{4}x=y$

$y=\frac{1}{4}x$ .
