Question

PLEASE HELP ME!!!!
Let F(x)=2x+2,g(x)=x^2, and h(x)=3/x-2
State the domain of the operation.
F(x)+g(x)

Answer 1

Domain: (-inf,inf)

Answer 2

what number makes this illegal to use? none.

Answer 3

so -inf, inf is the answer?

Answer 4

yeeeeeeeeeeeeeeeeeeeeeeees

Answer 5

f(x) + g(x) = x^2 + 2x + 2.
So the domain is \[(- \infty , \infty)\]

But I don't see where the fn h(x) is used, does the question have more in it?
