An archer fires two arrows into a raised target, as represented in the diagram below. about how much greater of an angle
did the archer need to use in order for the second arrow to land 7 feet higher than the first arrow?
arrow 2:
35 feet
arrow 1:
30 feet
o 1.0°
1.6°
o 6.0°

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.
