What is the maximum vertical distance between the line $y = x + 20$ and the parabola $y = x^2$ for $−4 ≤ x ≤ 5?$
What steps do I take to solve this? Do I have to use the distance formula and what do I do with the points it gave me?
If anyone could just bounce me in the right direction that would be neat. I can probably work an answer from there!
Also what's the distance formula to use here?
