I don’t have the definition of f. Please give the formula, a graph, or a table for f so I can evaluate it at x = −3.
If you want to do it yourself: substitute x = −3 into the expression for f(x) and simplify. Example: if f(x) = 2x^2 + 1, then f(−3) = 2(−3)^2 + 1 = 2·9 + 1 = 19. If f is piecewise, first determine which piece applies at x = −3. Also check the domain — f(−3) may be undefined.
