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:
0.0076, if you meant 4.125 divided by 0.03125 it would be 132
step-by-step explanation:
first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125
then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.
now you divide like you would normally would and get 0.0076

step-by-step explanation:
because where the point where the 2 lines intersect is (3,-1) the x value is 3
