Question

Graph the parabola.
y=-2x^2-12x-19

please give points

Answer 1

Hey there! :)

Answer:

y = -2x² - 12x - 19

Convert to vertex form by completing the square:

19 = -2x² - 12x

19 -18 = -2(x² + 6x + 9)

1 = -2(x + 3)²

y = -2(x + 3)² -1 Use this form to find the vertex and points:

Points:

X Y

-----------------------

-6 -19

-5 -9

-4 -3

-3 -1

-2 -3

-1 -9

0 -19
