Maths. Under functions on graphs of a parabola and a one to one function on the same set of axes when calculating the length how do i use the Turning point formula?

Answer 1

Please be more specific
To find the "length" of a parabola you will need to know integral calculus.
"turning point" formula of a parabola??
for any y = ax^2 + bx + c
the x of the vertex is -b/(2a), once you have the x
plug into the equation to get y

Answer 2

Ok thanks and Yep i also thought its calculus but some1 said its not so i got confused.
