Question 1117778: Write the standard form of the equation of the parabola that has the indicated vertex and passes through the given point. (Let x be the independent variable and y be the dependent variable.)
a. Vertex (-4,9); Point (0,25)
b. Vertex (-2,9); Point (-5,0)
Answer by greenestamps(13216) (Show Source): You can put this solution on YOUR website!

a. With vertex (-4,9) and y the dependent variable, the equation is

Plug in the x and y values of the given point to determine the value of the constant a.

The equation is

or

b. Use the same strategy.

Vertex (-2,9), so the equation is .

Plug in (x,y)=(-5,0) to determine the value of a.

Equation: or
