What is the equation for a parabola if the vertex is at (5,4) and goes through the point (3,-8)

Step-by-step explanation:

Hi there!

Given the vertex of a parabola and a point, it's easiest to organize the equation in vertex form:

where the vertex is located at and a is a numerical value

1) Plug the vertex into the equation

Plug in the vertex (5,4)

2) Solve for a

Plug in the given point (3,-8) and solve for a

Subtract 4 from both sides

Divide both sides by 4

Therefore, a=-3. Plug this back into :

I hope this helps!
