High Flying Airlines charges $20 to check a piece of luggage up to 40 pounds. Each additional pound over 40
pounds costs $0.25. The maximum weight for a piece of checked luggage is 80 pounds. Write a function to
represent the situation.

u would add it together and they whatever ur answer is that's what it is

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.
