Given that fx x 2 and gx x2 x find f g4 if it exists Se

Given that f(x) = x - 2 and g(x) = x^2 - x, find (f + g)(4), if it exists. Select the correct choice below and. if necessary, fill in the answer box to complete your choice. A. (f + g)(4) = (Simplify your answer.) B. The value for (f + g) (4) does not exist.

Solution

f(4) = 4 - 2 = 2

g(4) = 4² - 4 = 12

(f + g)(4) = f(4) + g(4) = 2 + 12 = 14 (ans)
