Question

check my last two questions?

1: For the function f(x)=(5-6x)^2, find f1. Determine whether f1 is a function.

2: Graph y=-2x^2+3 and its inverse.

Answer 1

@tcarroll010 ?

Answer 2

\(f^{-1}\) is an abuse of notation, because is presupposes that the inverse is a function
the inverse is not a function as you can see from the graph, it does not pass the "vertical line test"

Answer 3

so the equation is right and its not a function?

Answer 4
