Find the intervals on which f(x) = x4 − 8x2is increasing and decreas

1.	Find the intervals on which f(x) = x4 − 8x2is increasing and decreasing.
Answer» The function f(x) =x⁴ − 8x²is increasing in the interval (-2, 0)∪ (2,∞), and decreasing in the interval(−∞, −2) ∪(0, 2). Derivatives have many applications. One of the major applications of derivatives is determining the monotonicity of a given function in a specific interval.
