Answer:
(a) -24
(b) 2.6
(c) -2
(d) 119
Explanation:
It is convenient to let a calculator or spreadsheet do the function evaluations. That makes the composite functions easier to calculate.
(a) (f+g)(-2) = f(-2) +g(-2) = -19 +(-5) = -24
(b) (f/g)(3) = f(3)/g(3) = 26/10 = 2.6
(c) (f-g)(0) = f(0) -g(0) = -1 -1 = -2
(d) (f·g)(2) = f(2)·g(2) = 17·7 = 119
