How to do first derivative
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 − ...
