Question

What is the derivative graph of a parabola?

Answer 1

The formula for a parabola is `y = ax^2 + bx + c`, where `a, b and c` are numbers.
If you take the derivative of this:
`d/dx (ax^2 + bx + c) = 2ax + b`
So the derivative function is `y = 2ax+b`
If you grave this, you will always get a line, since this is a function of the first order.

Hope this helped.
