Question

I need help undertanding this question.

h(x) = x2 + 1 k(x) = x – 2

Evaluate 3h(2) + 2k(3) =

Answer 1

17

Explanation:

h(x) = x2 + 1 k(x) = x – 2

(h + k)(2) = 5 (h – k)(3) = 9

Answer 2

h(2) = 2^2 + 1 = 5
3h(2) = 3 (5) = 15

k(3) = x= 3 – 2 = 1
2k(3) = 2(1) = 2

so
3h(2) + 2k(3) = 15 + 1 = 16
