Question

If f(x)=2x^2+3 and g(x)=x^2-7 find (f+g)(x)

Answer 1

x^2+10

Explanation:

Answer 2

Answer is (f + g)(x) = 3x^2 - 4

Explanation:

Given,

f(x) = 2x^2 + 3

g(x) = x^2 - 7

To find : (f + g)(x)

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

= (2x^2 + 3) + (x^2 - 7 )

= 2x^2 + x^2 + 3 - 7

(f + g)(x) = 3x^2 - 4

Hence we get (f + g)(x) = 3x^2 - 4
