Answer:
First question: C
Graph question: D
Explanation:
First question asks us to identify the parameters of the variables in the vertex form of a parabola.
Recall the formula:
y = a(x-h)^2 + k
Using this formula we get -2 to be the (a), -3 to be the h, and the k to be 1.
In the graph, we can identify the vertex by where the graph is at its highest, or lowest point (depending on which way it opens). Because this graph open downwards, it has a maximum value, at (3,0).
Now plug this information into the equation, (along with the fact that it is reflected over the x axis)
we get :
y = -1(x-3)^2 + 0
simplify:
y = - ( x - 3 )^2
I hope this helps you, and as always, if you have any questions feel free to ask!
