.1. Given f= {(8, 2), (6, 2), (5, 0), (7, 4) (-1, 7) and g = {(5, 7), (3, 8), (0, -1), (2, 3), (-1, 6)}. Find the following. a) (fog)(3) b) (go f ) (5) c) (f of) (-1) d) (gog)(0).2. Use the graph of (x) and g(x), shown on the right, to evaluate each of the following. a) f(g(1)) b) f(g(-2) ) c) g(f(-4)) d) g(f (4) ) .3. If f(x) =3x +4 and g(x)=x -1, then determine each of the following, in simplest form. a) f(g(x)) b) g(f (x) ) c) f (f (x) ) d) gg(x))
