<h3>Answer: 4^x+5x-2</h3>

Add up the equations and combine any like terms. In this case, the like terms are -8 and +6 which combine to -2. Everything else is unlike terms so you leave them as is.

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

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

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

Answer:

\large\boxed{(f+g)(x)=4^x+5x-2}

Step-by-step explanation:

(f+g)(x)=f(x)+g(x)\\\\\text{We have:}\\\\f(x)=4^x-8,\ g(x)=5x+6\\\\\text{Substitute:}\\\\(f+g)(x)=(4^x-8)+(5x+6)=4^x+5x+(-8+6)\\\\(f+g)(x)=4^x+5x-2
