I’m year 11 and doing a old Maths paper at the moment and I’ve come to the exellence question.
I have a parabola that has the following co ordinates and i am in desperate need on how to make them in to a quadratic equation
(15,10) thats the maximum
there’s no Y intersept as the graph doessn’t show it
the answer sheet gives the equation:
y = -0.1(x-15)^2+10
any help on how they got that would be much appreciated
