Question

If f(x) = -4^x - 8 and g(x) = 5x + 6, find (f+g)(x)

Answer 1

-4^x + 5x - 2

Explanation:

By the additive property of function, (f+g)(x) = f(x) + g(x)

Given f(x) = -4^x - 8 and g(x) = 5x + 6

(f+g)(x) = f(x) + g(x)

= -4^x - 8 + 5x + 6

= -4^x + 5x - 2

Answer 2

(f+g)(x) = -4^x + 5x - 2

Explanation:

if f(x) = -4^x - 8 and g(x) = 5x + 6,

(f+g)(x) = f(x) + g(x)

= -4^x - 8 + 5x + 6

= -4^x + 5x - 2
