Answer 2

then type your problem in and it will show you the figure

Answer 3

Oh my gosh, I had been on that calc all day and didn't even think of it. Sorry it's finals tonight and I've been working all day

Answer 4

there is some work showing algebra, then you get to

Answer 5

yeah max/min value for x if you do calc too

Answer 6

Its cool glad to help anyway I can

Answer 7

Thank you guys, I got it. Just so tired and so much more to do

Answer 8

ah the algebra thing from middle school or whatever matches the y'=0=2ax+b, for that x value, ill be dam.. of course it does
