The value of (H + K) (2) = 5

Step-by-step explanation:

Given the functions:

H (x) = x² + 1

K (x) = x - 2

By adding the functions:

∴ (H + K) (x) = (x² + 1) + (x - 2) ⇒ Combine like terms.

∴ (H + K) (x) = x² + x - 1

To find (H + K) (2), substitute with x = 2

∴ (H + K) (2) = 2² + 2 - 1 = 4 + 2 - 1 = 5

∴ (H + K) (2) = 5
