Can a graph of a function ever have more than 1 x-intercept?

Answer 1

What about a parabola?

Answer 2

I think a parabola can have 2 x-intercepts..then is there a graph of a function where there's no x-intercept at all?

Answer 3

A parabola can be in any quadrant and not cross either x or y axis. Or it can have the vertex or a side on the y axis and not cross the x axis.
