Guided Practice Write the equation of the parabola in vertex form. The vertex is (−4, −3) and the parabola passes through the point (−1, −48). Create a rough sketch of the graph to use as a visual aid.

A.
y = −16(x + 3)^2 + 4

B.
y = −5(x + 4)^2 − 3

C.
y = −(x − 4)^2 − 3

D.
y = −5(x − 4)^2 − 3

B.

y = −5(x + 4)^2 − 3

Step-by-step explanation:

Use the vertex and another point on the parabola to find the value of a. Then substitute the vertex (−4, −3) and a into the vertex form, y = a(x − h)2 + k.

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.

good luck on your studies! : )
