Question

For the function f(x) = (3 – 4x)², find f^–1. Determine whether f^–1 is a function.

Answer 1

thank you so much

Answer 2

oh, okay

Answer 3

\[
f(x) = (3 - 4x)^2
\\y = (3 - 4x)^2
\\x = (3 - 4y)^2
\\\pm \sqrt{x} = 3 - 4y
\\\pm \sqrt{x} - 3 = -4y
\\\frac{\mp \sqrt{x} + 3}{4} = y
\\y = \frac{\mp \sqrt{x} + 3}{4}
\\f^{-1}(x) = \frac{\mp \sqrt{x} - 3}{4}
\]

Answer 4

Ugh

Answer 6

it's fine don't worry about it :)

Answer 7

Everything is correct except the last equation should also be +3
