Josh is putting up a fence around a garden that is next to a wall. He only has 54 feet of fence and the length of the garden must be 6 feet more than twice the width. In the system of equations that represent the situation, let l be the length of the garden and let w be the width:

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.

it's undefined because anything multiplied by 0 is 0. that said, 7 days is 168 hours
