Your calculator gives an answer of x=1.1578074156, y=2E13 when using ROOT or ZERO in the graphing mode. Give the coordinates of the xintercept your calculator has given you to the nearest thousandth. <<< ? I have no idea how to solve these. Someone please explain this! Thanks!

Reiny,
2E13 on most calculators means
2.0 x 10^13 which for all practical purposes is zero.
1.15780.. to the nearest thousandth is 1.158
So what is the xintercept ?
