Question

H(x) = x2 + 1 k(x) = x – 2 (h + k)(2) = 2 ⇒ 5 (h – k)(3) = Evaluate

Answer 1

Answer:

5 and 9

Step-by-step explanation:

(h + k)(x) = h(x) + k(x), then

h(x) + k(x)

= x² + 1 + x - 2 = x² + x - 1, thus

(h + k)(2) = 2² + 2 - 1 = 4 + 2 - 1 = 5

------------------------------------------------------

(h - k)(x) = (h(x) - k(x) , then

h(x) - k(x)

= x² + 1 - (x - 2)

= x² + 1 - x + 2

= x² - x + 3 , thus

(h - k)(3) = 3² - 3 + 3 = 9 + 3 - 3 = 9
