The table below gives the number of hours spent studying for a science exam(x) and the final exam grade (y).

Line of best fit equation:

Predict the exam grade of a student who studied for 6 hours.
Expected grade:

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.

step-by-step explanation:

it would rotate about 180 degrees.
