Plot the graph of f(x) = 3x^4 - 6x^2 on your calculator.
a) for which values of x is the function increasing
b) for which values of x is the function decreasing.
Thanks. I did it but I got it wrong.

f(x) = 3 [ x² - 1 ]² - 3 , df /dx = 2x [ x² - 1 ] = 0 at ± 1 & 0---> decreasing , increasing , decreasing , increasing
and note that the graph is symmetric about the y axis
