WebCritical - a critical number. So those are the different candidates. Now you could have a critical number in between that, where, say, the slope is zero, say something like this, but it is at the maximum or minimum. But what we can do is, if we can find all the critical numbers, we can then test the affect, the function of the value of the ... WebMay 5, 2024 · Find critical numbers (f '(x) = 0: 4 (x + 3)2 = 0 Multiply both sides by the denominator: 4 = 0 There are no critical numbers (maximums or minimums). This can be seen by graphing the function: graph { (x-1)/ (x+3) [-11.66, 8.34, -5.12, 4.88]} Answer link Related questions How do you find the stationary points of a curve?
