Describe the first derivative of a function

WebLet f be continuous on an interval I and differentiable on the interior of I . If f ′ ( x) > 0 for all x ∈ I, then f is increasing on I . If f ′ ( x) < 0 for all x ∈ I, then f is decreasing on I . Example. The function f ( x) = 3 x 4 − 4 x 3 − 12 x 2 + 3 has first derivative. f ′ ( x) = 12 x 3 – 12 x 2 − 24 x = 12 x ( x 2 − ... WebIf you use nested diff calls and do not specify the differentiation variable, diff determines the differentiation variable for each call. For example, differentiate the expression x*y by calling the diff function twice. Df = diff (diff (x*y)) Df = 1. In the first call, diff differentiates x*y with respect to x, and returns y.
