Question

F(x)=2x+3 and g(x)=x^2. find (f-g)(x)

Answer 1

(f - g)(x) = -x² + 2x + 3

Explanation:

Step 1: Define

f(x) = 2x + 3

g(x) = x²

(f - g)(x) = f(x) - g(x)

Step 2: Set up expression (Substitute)

(f - g)(x) = f(x) - g(x)

(f - g)(x) = 2x + 3 - x²

Step 3: Simplify

(f - g)(x) = -x² + 2x + 3
