Question
Please check, if there is something wrong please explain what I did wrong. Thank you!
Calculate the d^2y/dx^2.
y= e^-x + e^x
y' = e^x - e^-x
y'' = e^x + e^-x
Find the x-coordinace of all critical points of the given function. determine whether each critical point is a relative minimum, maximum, or neither by first applying the second derivative test, and, if the test fails by some other method.
g(x) = 2x^3 - 6x + 3
g'(x) = 6x^2 -6
g"(x) = 12x
max = -1
min = 1
critical = -1,1
