(f +g)(2) = 10
Solution:
Given f(x) = –4x
g(x) = 3x + 12
Let us first find f(2) and g(2).
Substitute x = 2 in f(2) and g(2).
f(2) = –4 × 2 = –8
g(2) = (3 × 2) + 12 = 18
Let us find (f + g)(2).
(f + g)(2) means adding combination of two functions.
(f +g)(2) = f(2) + g(2)
= –8 + 18
= 10
(f +g)(2) = 10
Hence, (f +g)(2) = 10.
