WebSo let's try out x equals one. It's in that interval. So when x equals one, I'll just write g prime of one is equal to four minus five. Four minus five, which is equal to negative one. So g prime of x is less than zero, g prime of x is less than zero. So our function, so we could say g is increasing here. e17 人感センサー斜め小型WebNow, follow the given steps to find its points of relative extrema: Step 1: Determine the derivative of f (x) f' (x) = 6x 2 - 6x Step 2: Equate the derivative to 0, i.e., f' (x) = 0 to find the critical points. f' (x) = 0 ⇒ 6x 2 - 6x = 0 ⇒ 6x (x - 1) = 0 ⇒ x = 0, or x = 1 Therefore, x = 0 and x = 1 are the critical points. e17口金人感センサーWeb6 uur geleden · I have an image with the name image1.png.
