im not sure how to do this problem. given the following function, state the x-coordinate of any relative extrema and identify as a maximum or minimum. justify your answer. f(x)= e^x^2-4x so x^2-4x is the exponent for e.. thank you.

Did you do something for it? Start by taking the derivative ..
okay.. so the derivative is e(2x-4)... uhhh...and then i need to set the equatioin = to 0? and then what would i do after that?

ooh crap.. 2x-4e^x^2-4x is the derivative. should be correct i hope.

uhh i think i set it equal to 0 but im really not sure what else to do with this problem.. my calc teacher can't teach >.<
