If Jasper installs a floor himself, it will take him 7 hours. Working with Yolanda, it will take them 3 hours. A table showing Rate in part per hour, Time in hours, and Part of Floor Installed. The first row shows Jasper, and has, StartFraction 1 Over 7 EndFraction, 3, and question mark. The second row shows Yolanda and has r, 3, and 3 r. If they work together, what is the missing value in the table that represents the part of the floor Jasper will install? StartFraction 1 Over 7 EndFraction times 3.(3) StartFraction 1 Over 7 EndFraction times r. r 7r 7(3)

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:

a) 0,0; 1,1; and 2,2

step-by-step explanation:

these have the exact same coordinates, thus they are the correct function.
