can you write a quadratic equation in rectangular form?

Question

for example, if you have x(t)=1.25x^2-13x-37, how would you put that in rectangular form (eliminante "t" and just have y=f(x))?

Answer 1

Are you sure it isn't x(t)=1.25t^2-13t-37? If so, then your answer would be f(x) =1.25x^2-13x-37
