Best ResponseYou've already chosen the best response.0height of the parabola in inches: Take the formula to be y = ax^2 The focus of the parabola is 2 inches up, which means a/4 = 2 ==> a = 8... the equation is: y = 8x^2

Best ResponseYou've already chosen the best response.0Replace the 2 with a 6. Which means a/4 = 2 ==> a = 8.  a/4 = 6 ==> a = 24. y = 24x^2

Best ResponseYou've already chosen the best response.0Whoops, y = ax^2 is the formula, I guess whatever the 'x' is, but at least you have the answer. Off to other post, later, welcome.
