Hint: that shaded area is 2-dimensional.  How many dimensions in lines?  How many dimensions in planes?

anonymous · Answer

so it is a plane right?

anonymous · Answer

Yes, that's correct.  If the equation were something like y = x^2 where it just touches the x-axis, nothing goes below, but as soon as there is something below, it is a 2-dimensional plane.
