Step-by-step explanation:

Step 1: Define

Identify

f(x) = 4x + 1

g(x) = x² - 5

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

Step 2: Find

1. Substitute in functions:                                                                                     (f + g)(x) = 4x + 1 + x² - 5
2. Combine like terms:                                                                                         (f + g)(x) = x² + 4x - 4

Answer 2

Answer:

B  

Step-by-step explanation:  6  18  11  18

f(x)=4x+1 and g(x)=x^2 -5

f(x)=     4x+1

g(x)=x^2 -5      just add these two equations

(f+g)(x)  =  x² + 4x +1 - 5

(f+g)(x)  =  x² + 4x - 4     B
