Answer:
(f + g)(-6) = 37
Step-by-step explanation:
Points to remember
If f(x) and g(x) be the two functions, then
(f + g)(x) = f(x) + g(x)
It is given that, f(x) = x + 1 and g(x) =x^2 - x
To find the value of (f + g)(-6)
(f + g)(-6) = f(-6) + g(-6)
f(x) = x + 1
f(-6) = -6 + 1 = -5
g(x) =x^2 - x
g(-6) = (6)^2 - (-6)
= 36 + 6 = 42
(f + g)(-6) = -5 + 42 = 37
