Question

If f(x) = x^2+ 1 and g(x) = 3x-1, find (f-g)(x)

Pls help!!!

Answer 1

(f-g)(x) = x^2 - 3x + 2

Explanation:

If f(x) = x^2+ 1 and g(x) = 3x-1

Then (f-g)(x) = (x^2+ 1 )(-(3x-1)

(f-g)(x) = x^2 + 1 - 3x + 1

(f-g)(x) = x^2 - 3x + 2

Answer 2

x^2 -3x+2

Explanation:

If f(x) = x^2+ 1 and g(x) = 3x-1,

(f-g)(x) = x^2 +1 - (3x-1)

Distribute the minus sign

= x^2 +1 -3x+1

Combine like terms

= x^2 -3x+2
