for the given functions f and g, find the specified value of the following functions and state their domains:

Question

f(x)=x-5; g(x)=2x^2

a.(f+g)(3)=
b.(f/g)(3)=

Can someone help me figure this out? pleeeease????

Answer 1

form your functions,

(f+g)(x) = x-5 + 2x^2
so (f+g)(3) = 3-5+50 = 48

do the same thing for your second question
