b must equal Zero because the parabola is not shifted left or right. So that leaves us with the equation:

c is 185 because when an x value of 0 is subbed and a y value of 185 is subbed in c is denoted to be 185.

That leave us to find a.

Sub in 35, 0 zero for x and y values respectively and you will find a = -185/1225. Leaving us with the equation:

And it seems to work fin when I sub values in I havn't looked into simplifying it.

]]>(a) Use the y-axis as the axis of symetry for the parabola and deveolp a rule which will produce a parabola to fit these requirements.

Can any1 help?]]>
