Question

PLEASE HELP!!
The vertex of this parabola is at (-2,-3). When the x-values is -1, the y-value is -5. What is the coefficient of the squared expression in the parabola's equation?

a. -8
b. 2
c. 8
d. -2

Answer 1

here is the graph that comes with the question

Answer 2

Is this a vertical parabola or a horiz. one? What are the coordinates of the vertex? What are the coordinates of another point which lies on the parabola?

Write the vertex form of a parabola according to whether this one is vertical or horiz.

Doing this should enable you to find the coefficient of the squared quantity.

Please go back to the previous question if you can; review it and transfer at least some of what you have learned to this new question.
