I tried this:
Explanation:
Let us plot our position function:
graph{2x^2-8x+10 [-10, 10, -5, 5]}
We can see that at
I would derive your position function to find the velocity::
at
the minus sign tells us that the velocity is towards the left (having choosen the positive
at
this time the positive value of the velocity tells us that it is twards the right.
