From the diagram the quadratic has roots at $x = 0$ and $x = 15.$ What is the equation of a quadratic with roots of $x = 0$ and $x = 15?$ What is another quadratic with these roots? It might help to look here or here. What is the equation of a quadratic with roots of $x = 0$ centimeters and $x = 15$ centimeters and maximum value of $f(x) = 30$ centimeters? Penny
