Write the equation of a parabola with a vertex at (-5, 2) and a directrix y = -1.

Options are:

y minus 2 equals one-twelfth times the quantity x plus 5 squared

y minus 2 equals one-fourth times the quantity x plus 5 squared

y plus 2 equals one-twelfth times the quantity x minus 5 squared

x plus 5 equals negative one-twelfth times the quantity y minus 2 squared

First one

Step-by-step explanation:

(x - h)² = 4p(y - k)

(h,k) = (-5,2)

p = 2 - -1 = 3

(x - -5)² = 4(3)(y - 2)

(x + 5)² = 12(y - 2)

y - 2 = (1/12)(x + 5)²

step-by-step explanation:

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.
