Question 1131430: I have been asked to use a graphing calculator to approximate the location of the local maximum on the graph of y=x^3+12x^2-105x-3. values must be correct to the nearest hundredth. I feel like I am doing something wrong. I have a TI-84 Plus C Silver Edition calculator. I've tried to zoom in and I can't quite see the bottom nor top of the graph. It makes it hard to satisfy the question, because I can't see it. I've never done something like this before, so it's...frustrating. Answer by josgarithmetic(39617) (Show Source):
You can put this solution on YOUR website! Window should be about from X negative 20 to 0 or further right.
Y should be maybe about 0 to 1300. The local maximum appears to be near (11, 1270).
