Identify the vertex for the graph of y = −2x2 − 12x 1.
(−3, 19)
(−3, 55)
(3, −53)
(3, −47)

(-3,19)

Step-by-step explanation:

Here the given function is,

Since, the standard equation of a quadratic function is

Where (h,k) is the vertex of the function.

On comparing the equation of given function with this standard form,

We get, the vertex of the given function is (-3,19)

⇒ First option is correct.

10 cm

step-by-step explanation:

if the polygon is a rectangle, then the perimeter is x+x+y+y. using the values that you gave, the perimeter is 3+3+2+2=10cm.

y=20x
