Concept

When talking about functions, the $x-$intercepts are the zeros of the function. Sometimes, only one coordinate of these points is referenced. For example, if the $x-$intercept lies at $(a,0),$ it can be said that the $x-$intercept is at $x=a.$ The same is true for the $y-$intercept. A relation can have several intercepts. A function can have multiple $x-$intercepts, but it can only have one $y-$intercept.
