I’m not sure how to read "(x8)2" — could you confirm the intended expression? Common possibilities and their values at x = −4:

- If f(x) = (x + 8)^2, then f(−4) = (−4 + 8)^2 = 4^2 = 16.
- If f(x) = (x − 8)^2, then f(−4) = (−4 − 8)^2 = (−12)^2 = 144.
- If f(x) = (x/8)^2, then f(−4) = (−4/8)^2 = (−1/2)^2 = 1/4.
- If f(x) = (x^8)^2 = x^16, then f(−4) = (−4)^16 = 4,294,967,296.

Tell me which one you meant and I’ll confirm.
