If F(x)=2 and g(x)=x^2+1,what is g(3)+f(4)
notka56 [123]

Answer:

12

Step-by-step explanation:

for g(3) replace x with 3 and for f(4) since f(x) is a constant function the value won't change so you put 2 then add both functions up

g(3) = 3^2 + 1 ➡ 10

f(4)= 2

10 + 2 = 12

5(w + 4) is your answer.
