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

please give points

Hey there! :)

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:

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5
