Justine correctly used completing the square to rewrite the quadratic expression 2x2 – 12x + 25 as 2(x - 3)2 + 7.
After seeing the new form of the expression, Justine
said that the expression had a minimum value of 7
when xis -3. Is Justine right?

multiple all that

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.
