SOMEONE HELP WITH CALCULUS PLEASE ;-;

If you ever want to do something useful, you'll need it.

Advanced math is not useful unless you plan on being an engineer or something.

that's why i said if you ever want to do something useful, you'll need it

a) For what values of x does f have a relative maximum? why?
when x = 1 because it's the highest point before y approaches infinity

b) For what values of x does f have a relative minimum? why?
when x = -1 and x = 3 because it's the lowest point before y approaches infinity

c) On what intervals is the graph of f concave upward? Use f' to justify your answer.
between x = -1  to x = 3 because the slope of the tangent line at x = 1 is zero and the points surrounding decrease to zero and then increase from zero.

d) Suppose that f(1) = 0. In the xy-plane provided, draw a sketch that shows the general shape of the function f on the open interval 0 < x < 2.
too much thinking.

woah, that's actually what I got.

i ended up getting that one right, but got the next one (that I didn't post) was ridiculously incorrect.

I'm going to scan and post it now.

a)x = 4 because the slope changes from positive to negative at that point.
b)x = -2 " " negative to positive at that point

oh shit, contradicting answers ;-;

I'm inclined to listen to jimvers because creeper has given me incorrect answers in the past.

im right. think about it.

if you have a curve like


/'\

/ is positive slope ' is the maximum then \ is negative slope.

JMV is correct, sam.

[Sam]

Good because I agreed with JMV when I thought it through yesterday. I'm fairly certain I got everything right on that page.
