Quadratic functions “q” and “w” are graphed on the same coordinate grid the vertex of the graph of “q” is 11 units below the vertex of the graph of “w”. Which pair of functions could have been used to create the graphs of “q” and “w” A. Q(x) = 11 x^2 and w(x) = x^2
B. Q(x) = x^2 +11 and w(x) = x^2
C. Q(x) = -11x^2 and w(x) = x^2
D. Q(x) = x^2 -11 and w(x) = x^2

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.
