Answer:
Explanation:
they nicely give you the formula you need
f(x) = a(x-h)^2 +k
also they give
f(x) = 7

and they want the vertex at (3,5)
the vertex is in the form of P(h,k)
so add that info to the given info in the formula given
f(x) = 7(x-3)+5
I'll add the graph of both parabolas so you can see they are similar
