Question

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

Answer 1

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

Answer 2

B. x² + 4x - 4

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
