PLEASE HELP!! WILL MARK BRAINIEST !!
SOVA2 [1]

Answer:

(f+g)(2) = 10

Step-by-step explanation:

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

g(x)=x-2

(f+g)(x) will be sum of f(x) and g(x)

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

we have to find  (f+g)(2), for that we will put x = 2

(f+g)(x)  = 2x^2+4x - 2

(f+g)(2)  = 2*2^2+2*2 - 2\\(f+g)(2)  = 2*4+4 - 2\\(f+g)(2)  = 8+4 - 2 = 10

Thus,  (f+g)(2) is 10.
