If f(x) = -2x -5 and g(x) = x^2 + 1, find f(g(x)).
-2x-7
If f(x) = 5 + 3x and g(x) = 5 - 9x, find f(g(2)).
-34
Recalling function notation, we want x to be w. Therefore, if f(x) = (3x + 5) / 2, find f(w).
3w+5/2
If f(x) = -2x - 5 and g(x) = x^2 + 1, find f(f(x)).
4x+5
If f(x) = 5 - 2x and g(x) = -4x + 2, find g(f(x)).
8x - 18
