If the dot is multiplication, then f(2x -x) = f(x) * f(x) f(x) = f(x) * f(x) u = u^2; could solve by quadratic formula to find u = 0 or 1. Cannot be 0. f(x) = 1 assuming f(x) is restricted to real and complex numbers.

Height of trapezoid (assuming bases are parallel) is (1/4)(12) = 3 in. A = (1/2)(h)(b1 + b2) = (1/2)(3)(12 + 4) = (3/2)(16) = 24 in^2 P = 5 + 5 + 4 + 12 = 26 in.
