Question

Select all input values for which
\[g(x)=4\].

Answer 1

I don't see the definition of g(x). Please paste the function (or the full problem/image).

If you want general guidance: to find all x with g(x)=4 you

- Set g(x)=4 and solve that equation for x.
- Use algebraic steps appropriate to the type of g (rearrange for polynomials/rationals, take logs for exponentials, use inverse trig for trig functions).
- Watch for domain restrictions and extraneous solutions if you squared both sides or did other nonreversible steps.
- If g is invertible on its domain, you can compute x = g^{-1}(4).

Paste g(x) and I’ll solve it step by step.
