Among the early insects were giant dragonflies with wingspans of 7000 millimeters. How many 25
centimeter pieces of wood would you need to lay side by side to equal this length?

7000mm=700cm

700cm÷25cm=28

I would need to lay 28 pieces of wood side by side to equal this length.

thats not a system of equations, that is a solution

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.
