Best ResponseYou've already chosen the best response.1ok so set dy/dx = 3 dy/dx = 2(x^24) + 2x(2x1) = 3 > 6x^2 2x 11 = 0 use quadratic formula to get x_coordinates

Best ResponseYou've already chosen the best response.1check your computation of quadratic formula...the above function gives correct xvalues...1.197, 1.53

Best ResponseYou've already chosen the best response.0Well. Here's what I did and results: Found dy/dx=6x^22x8. Factored out 2 so 0=2(3x^2x4) Oh, didn't do quadratics. Slip of the mind, sorry. Factored the equation so x=4/3 amd x=1.

Best ResponseYou've already chosen the best response.1oh i see...the only part that is wrong is you assumed it equaled 0 but RHS should be 3 6x^2 2x 8 = 3 then factoring out the 2 doesn't really help
