    So you want to find the inverse of \(f(x)=4+(-13x+9)^2+3\)?

    I mean \(f(x)=4(−13x+9)^2+3\).

    If so, then you need to know that this is NOT a one-to-one function. Thus it doesn't have an inverse, except for some strict domains (at which the function is one to one).

    is it because it's squared?

    Yes, parabolas are not one-to-one functions.

    so parabolas will never be one- to -one functions, so the answer is no solution?

    As I said, in general the given function doesn't have an inverse. However, you can work on "some restricted domain" of the function that's one-to-one.
