SOLVED:Use a graphing utility to graph each function over the indicated interval and approximate any local maximum values and local minimum values. Determine where the function is increasing and where it is decreasing. Round answers to two decimal places. f(x)=x^4-x^2 (-2,2)

SOLVED:(a) Use a graphing utility to draw a graph of each function. (b) For each x-intercept, zoom in until you can estimate it accurately to the nearest one-tenth. (c) Use algebra to determine each x-intercept. If an intercept involves a radical, give that answer as well as a calculator approximation rounded to three decimal places. Check to see that your results are consistent with the graphical estimates obtained in part (b). N(t)=t^7 8 t^4 16 t
