# What is the equation of the parabola that has a vertex at # (-15, -6) # and passes through point # (-19,7) #?

# y = 13/16 (x + 15 )^2 - 6 #

The equation of a parabola in vertex form is :

where (h , k ) are the coordinates of the vertex.

Given the point (- 19 , 7 ) that lies on the parabola allows substitution into the equation to find a .
