Question

Find the inverse of the function f(x) = 4x – 2.
Then graph the function and its inverse.
​

Answer 1

Y = 1/4x + 1/2

Explanation:

The inverse is found by reflecting the graph across the y=x line. In the equation, this result by switching x and y then solving for y.

Y =4x-2

X=4y-2

X+2=4y

(X+2)/4= y

1/4x +1/2 =y
