Question

F(x)=1-2x part e) find f^-1 (x)

Answer 1

y = 0.5 - x/2

Explanation:

The -1 power means the inverse function of f(x). This means that you will write the function in terms of x and y, replaces x's with y's and vice versa, and then write the new function in terms of x.

f(x) = 1 - 2x

y = 1 - 2x

Switch variable places.

x = 1 - 2y

Solve for y.

2y = 1 - x

y = 0.5 - x/2
