Which statement is true about inverse functions? A) If a function f is one-to-one, then f has an inverse function f-1.
B) In a one-to-one function, each x-value corresponds to only one y-value. and each y-value corresponds to only one x-value.
C) The graphs of f and f-1 are reflections of each other about the line y = x.
D) All three statement are true.

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17

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.
