Let f(x) = 3x2 + 1 and g(x) = - 2x +6. Find the following. (f-9)(-2) (f-9)(-2) = Let f(x) = x2 - 20 and g(x) = 10 - x. Perform the composition or operation indicated. (f9)(-7) (19)(-7)=0 Let f(x) = 2x - 1 and g(x) = je Find (f+g)(x), (-9)(x), (fg)(x), and 19. (x). Give the domain of each. (f +9)(x) = (Simplify your answer.) (f-g)(x) = (Simplify your answer.) (fg)(x) = (Simplify your answer.) (h) = (simplify your answer) The domain off+g is (Type your answer in interval notation.) The domain off-g is (Type your answer in interval notation) The domain of fg is (Type your answer in interval notation) The domain of is (Type your answer in interval notation.) f(x + h) – f(x) For the function f(x) = x2 -9, find (a) f(x + h), (b) f(x + h) – f(x), and (c) h (a) f(x +h) = (Simplify your answer.) (b) f(x + h) – f(x) = (Simplify, your answer.) f(x+h)-f(x) (c) h (Simplify your answer.) Let f(x) = 4x - 1, h(x) = - X+4. Find (f o h)(-4). (fo h)( - 4) = 0
