Question

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:

Answer 1

So this is what I got for (f*g)= 2x(sqrt)4x-5 + 3(sqrt)4x-5
for f+g= 2x+3+(sqrt)4x-5

is that right?
