WebJul 9, 2024 · Here’s how: Take a number line and put down the critical numbers you have found: 0, –2, and 2. You divide this number line into four regions: to the left of –2, from –2 to 0, from 0 to 2, and to the right of 2. Pick a value from each region, plug it into the first derivative, and note whether your result is positive or negative. WebFeb 5, 2024 · But if we find multiple critical points, then we need to find the derivative’s sign to the left of the left-most critical point, to the right of the right-most critical point, and between each critical point. Let’s continue with one of the previous examples, looking at the sign of the derivative between each critical point. ...
