Question

Adition and subtraction of functions

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

(f + g)(x) =

x^2 + x -4

x^2+x+4

x^2-X+6

x^2 + x + 6​

Answer 1

(f + g)(x) = x² - x + 6

Explanation:

Answer 2

(f + g)(x) = x² - x + 6

Explanation:

Step 1: Define

f(x) = x² + 1

g(x) = 5 - x

Step 2: Find (f + g)(x)

(f + g)(x) = x² + 1 + 5 - x

(f + g)(x) = x² - x + 6
