Decreasing on $(-\infty,-1)\cup(0,1)$ Increasing on $(-1,0)\cup(1,\infty)$

Work Step by Step

We are given the function: $f(x)=3x^4-6x^2$ Graph the function. From the graph we find: $f$ is decreasing on $(-\infty,-1)\cup(0,1)$ $f$ is increasing on $(-1,0)\cup(1,\infty)$ Check the result using a table of values:
