Precalculus - Worksheet 4 Page 2/2 5. Given the function f = ((-3,4), (-2,2), (-1,0), (0,1), (1,3), (2,4), (3,-1)) and the function g = {(-3, -2), (-2,0). (-1, -4), (0,0), (1, -3), (2,1), (3,2)), compute the following values. (a) (fog) (3) (c) (g . f) (3) (e) (g . f . g) (0) ( b ) (f of ) (0 ) (d) (g . g)(-2) (of (f (f ( F ( F(1))) ) ) 6. Use the graphs below to compute the following values. (a) (go f) (1) (c) (g . f) (2) (e) (f . f) ( 1) (b) (fog) (3) (d) (f . g)(0) (f) (g . g) (1) M - -L- -. f(x) g (x ) 7. For each given pair of functions, compute (g . f) (0), (f . g) (), and (f . ) (-2). (a) f(x) = 4 - 3x, g(x) = 1x1 (b) f (x) = 4x + 5, g(x) = vx (c) f (x) = 6-x-x2, g(x) = xvx+10 (d) f(x) = _,9(x) = x2+1 4x 8. For each given pair of functions, compute and simplify (g . f)(x), (f . g) (x), and (f of) (x ). (a) f(x) = 2x + 3, g(x) =x2 -9 (b) f (x) = x2 - 4, g(x) = 1x1 (c) f(x) = 3- x2, g(x) = Vx+1 (d) f (x) = = 2x+1) 9(x) = 2x+1
