A hiker wants to estimate the height of a mountain before attempting a climb to the top. Her first
measurement shows an angle of elevation to the top of
the mountain as 63.4º. Her second measurement, taken
950 ft closer to the base of the mountain, yields an
angle of elevation of 75.3º. From these measurements,
estimate the height of the mountain. Round to the
nearest hundred feet.

answer is x<

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.
