Question 804903: the question says " suppose a parabola has a vertex (-8,-7) and also passes through the point (-7,-4). Write the equation of the parabola in vertex form; y=a(x-h)^2 +k
Im soooo confused Ive tried everything and it just isnt clicking if you could help I would honestly appreciate it! :( thank you !

You can put this solution on YOUR website!
y=a%28x%2B8%29%5E2-7
now plug (-7,-4) into the above equation
-4=a%28-7%2B8%29%5E2-7
3=a%281%29%5E2
a=3
now plug it all together
y=3%28x%2B8%29%5E2-7
