Define the derivative function of a given function. D dxf gx f gxgx d d x f g x f g x g x Step 2. And came up with this derivative.
See if you can guess what the third derivative is or the fourth.
On a derivative graph youve got an m-axis. The d is not a variable and therefore cannot be cance. The upward or downward curve of the graph of a function concavity test suppose f is twice differentiable over an interval I. For instance if f x 5x 1 then the slope is just 5 everywhere so f x 5.
