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
