The graph of any quadratic equation is a parabola. A parabola will look like either a right-side-up U'': or an upside-down U.''. The places the parabola crosses the x-axis are called the x-intercepts, just like with linear equations.ince not all quadratic equations have solutions, the graph might not have any x-intercepts. It could look like this, for example: The y-intercept is the value we get when we plug x = 0 in to the equation ax 2 + bx + c. When we do that, we find. a (0) 2 + b (0) + c = c.
