Here's a graph of the function: Note that it is the cosine function, but stretched in the vertical direction by the factor $2$ and “compressed” in the horizontal direction by the factor $3$.

1 Critical points are not where the function is $0.$ You want to find the points where the derivative is $0.$ Unfortunately, your function does not happen to be differentiable at $2$ or $-2,$ so you …

Find the critical points of a function $f (x) = x\sqrt {x-a}$. A function $f (x)$ is said to have critical points at points $c$ such that $f^\prime (c)$ is $0$ or undefined.

Feb 3, 2019 · 1 How do you know if a function has infinite critical points? I have learned that you can find critical points by setting the derivative of separate axes to 0 and solving, but I also …

I am having difficulties in understanding the steps/method required to find the critical points of a function using the method of Lagrange multipliers. I have read through my text book and tried …

Oct 7, 2021 · Using the second condition gave me 2 other critical points: $ (-1,\frac {1} {2})$ and $ (-1,-\frac {1} {2})$ So now that I know what are the critical points, I want to classify them (local …

Usually you would define a "critical point" as the zero-points of the first derivative of your function. Since this functions first derivative has no zero-point, the critical point you search for is …
