How do I find the range of f(x)=x+4 x+2 I know that to find the domain I need to set the denominator =0 and solve. But i'm...

What is the domain of the function using interval notation?

I was given a graph of a quadratic function (parabola) and told to find the domain and range in INTERVAL notation. So lets say the vertex is (4,2) and there are no intercepts(?). I'm confused...
