There can be exactly one x intercept also, you know.
>>262934
Technically it can have 1 x intercept if the vertex lies on the x-axis.

Another way to define it is when x is tangent to the x-axis. When you find a line tangent to an equation at a point, you DO use two points to determine the slope of that line, but we find this by having the distance between those two points approach 0 which leaves us with 1 point.

>x is tangent to the x-axis
I mean the equation, but you know, whatever.
