Name: ______________________________________ HW 2/6: Function Notation 1. Evaluate the following expressions given the functions below: = -3x + 1 = x2 + 7 g(x) f(x) = = = a. b. c. g(10) f(3) h(–2) d. Find if g(x) = 16 e. Find if = f. Find if = 23 x x h(x) x j(x) –2 2. Fill in the table for the function from the given domain. . . . x f(x) x f(x) x f(x) input output input output input output -4 -2 -2 -2 -1 -1 0 0 0 2 1 1 4 2 2 3. Evaluate the function with the following domain {-3, 0, 2} b. 4. Given this graph of the function f(x): Find: a. = b. = c. = d. = f(–4) f(0) f(2) f(-5) e. what is when = 4 f. what is when = -1 x f(x) x f(x)
