Question

Find the f-1(x). State any restrictions on the domain of f-1(x). f(x)=x2-6x+1, x≥3

Answer 1

you have y=x^2-6x+1
or you can write this as 0=x^2-6x+1-y
Solve this for x.

Answer 2

You could use the quadratic formula

Answer 3

Thank you, this was a new one for me. I appreciate it.

Answer 4

You will get two options for x
use the fact that x is greater than or equal to 3 to choose the appropriate choice

then when done replace x with f^(-1)(x) and replace y with x
