Best ResponseYou've already chosen the best response.1\[y=a (\frac{ b }{ 2 }+x)(\frac{ b }{ 2}x)\] Is that a good start?

Best ResponseYou've already chosen the best response.1Looks good, plugin the point \((0, h)\) and find the value of \(a\)

Best ResponseYou've already chosen the best response.1y= a (b/2+x) (b/2x) Or y= a (b/2+x) (b/2x) Should I do a or a I should do a because it's a negative quadratic

Best ResponseYou've already chosen the best response.1Ok I got a= 4h/b^2 Shouldn't be a negative value?

Best ResponseYou've already chosen the best response.1so the equation is \[y=\dfrac{4h}{b^2} (\frac{ b }{ 2 }+x)(\frac{ b }{ 2}x)\] simplify if you want to

Best ResponseYou've already chosen the best response.1do you mean y = (4h/b^2)x^2+h ?
