Worksheet 4 - Operations on Functions ($3.5) 1. 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) (f+ g)(-3) (d) (g - f) (3) ( b) (f - g ) (2 ) (e) () (-2) (c) (fg)(-1) (1) (= (3) 2. Use the graphs below to compute the following values. (a) (f + g)(1) (d) (fg) (4) ( ) (f - g) (2) (e) () (1) (c) (g- f)(3) (1) (2(4) f(x) g (x) 3. Compute (f + g) (2), (f - 9)(-1), (fg) (), and () (o). (a) f(x) = x2 - x, g(x) =12 - x2 (b) f (x) = vx+ 3, g(x) = 2x-1 (c) f (x) = 2x, g(x) = 2x + 1 (d) f (x) = x2, g(x) = 4. Compute and simplify (f + g) (x), (f - g)(x), (fg)(x), and () (x). (a) f(x) = x2, g(x) =3x-1 (b) f (x) = x2 - 4, g(x) = 3x+6 (c) f (x) =5,9(x) =- (d) f (x) = x, g(x) = Vx+1
