NAME:_____________________ Function Notation Practice DATE:___________ 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. = e. Find if g(x) = 16 f. Find if j(x) = 23 j(a) x x 2. Combine the following functions and evaluate when necessary. = 6x + 8 = 5x - 12 = 2x = 3x2 + 7x - 1 f(x) g(x) h(x) j(x) a. Find g(x) + f(x). b. Find g(x) - f(x). c. Find f(x) + j(x). d. Find (g*h) (x). e. Find (j - g)(4). f. Find (f/h)(x). g. Find (f*h)(2) h. Find f(2) * h(2) Translate the following statements into coordinate points, 3. then plot them. a. = 1 f(–1) b. = 7 f(2) = c. f(1) –1 d. = 0 f(3) e. Is a function? How do you know? f(x)
