SOLUTION: Find the equation of the parabola if axis is horizontal, vertex on y axis and passing through (2,4) and (8,-2)

Question 1018040: Find the equation of the parabola if axis is horizontal, vertex on y axis and passing through (2,4) and (8,-2)
Answer by josgarithmetic(39620) (Show Source): You can put this solution on YOUR website!
Parabola with horizontal SYMMETRY axis, ; if vertex is ON the y-axis, then h=0, and the form is .

Next, your two given points on the parabola will give you the system of equations,

which you can work with...

and then and solve for k, before solving for a. That is HOW to continue. You can finish this.
