Consider the point. (4, 5, 6) what is the projection of the point on the xy-plane? (x, y, z) = what is the projection of the point on the yz-plane? (x, y, z) = what is the projection of the point on the xz-plane? (x, y, z) = draw a rectangular box with the origin and (4, 5, 6) as opposite vertices and with its faces parallel to the coordinate planes. label all vertices of the box.

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
