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

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

Step-by-step 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
