When graphing y = 2x2 + 35x + 75, which viewing window would allow you to see all of the intercepts and the minimum as closely as possible?
the x-axis from –20 to 5, and the y-axis from –80 to 80
the x-axis from –80 to 80, and the y-axis from –20 to 5
the x-axis from –5 to 20, and the y-axis from –80 to 80
the x-axis from –80 to 80, and the y-axis from –5 to 20

answer: d. $20

step-by-step explanation:

just took the test

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:

d. corresponding side lengths in similar triangles are proportional in length.
