@zarkam21 Do you know the equation of the parabola in vertex form? Or, are you able to write the general equation of a parabola if you're given the vertex?

OpenStudy (mathmate):

Since you left, I'll leave you some hints. You can take it from there: 1. Write the equation of the parabola, given that the vertex is at (3,2). The general equation of a parabola (that opens up or down) with vertex at (h,k) is given by: y=a(x-h)+k 2. Once you have the equation, the parameter "a" remains unknown. Since you know the parabola passes through (4,6), which means when x=4, y=6. You would put the values into the equation to solve for "a". The substituted equation looks like this: 6=a(4-h)+k Since h and k have been found before, you can solve for the value of a to complete the equation.
