Math question again?

I don't really understand this. The problem says that I need to find the domain of the function: f(x)=x^2+1, 0 £ x £ 5 (the £ is supposed to be the 'less than or equal to sign' but it didn't come out right) Are there supposed to be to domains? And if so, is this right: (-infinity,... show more I don't really understand this. The problem says that I need to find the domain of the function:
