The intercepts to a curve are the lengths of the axes from the origin, at which the curve intersects the axes.
The given parabola intersects the x-axis two times, while the y-axis just once.
So the given parabola will have 2 x-intersepts, and 1 y-intercept.
Consider that the parabola intersects x-axis at (-2,0) and (4,0).
So the x-intercepts are -2 and 4.
Similarly, observe that the parabola intersects the y-axis at (0,-8).
So the y-intercept is -8.
