Answer:
Step-by-step explanation:
Hi there!
Because we're given the vertex of the parabola, we can determine its equation in vertex form:
where the vertex is 
Plug in the vertex (0,0)
Now, we must solve for a. Plug in the given point (-2,3) and solve for a:
Therefore, the value of a is 
. Plug this back into 
:
I hope this helps!
This is so hard not gonna lie :0
Answer:
f(x) = -3(x - 5)^2 + 4
vertex (5,4)
Step-by-step explanation:
f(x) = -3x² +30x - 71
f(x) = -3(x² +-10x) - 71
f(x) = -3(x² +-10x+5^2-5^2) - 71
f(x) = -3(x² +-10x+5^2) -3(-5^2) - 71
f(x) = -3(x² +-10x+5^2) + 4
f(x) = -3(x - 5)^2 + 4
vertex (5,4)
