What is the mode of the following number sequence:
1,2,3,4,5,6,7,8,9

The answer is None there is no mode for the question.

Step-by-step explanation:

We know this because a mode is the number that occurs the most and because all the numbers occur the same amount there is no mode.

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.
