Question

Do I solve for f and solve for g then find the domain? or do I find the domain of each first then combine them to find the shared domain f+g and f*g?

Suppose that the functions of f and g are as follows
f(x) = 2x+3
g(x)= (sqrt 4x-5)
Find f*g and f+g. Then give their domain using interval notation

(f*g)(x)=
Domain of f*g:

(f+g)(x)=
Domain of f+g:
