So let's first, let's take the first derivative, g prime of x, it's gonna apply the power rule a lot, four times negative one is negative four, x to the third power, plus, okay, so you're gonna have two times six is plus 12, x to the first power, you just write it as x, and then minus two, I could say minus two, x to the zeroth power, but that's just minus two, and then the derivative of negative three of a constant is just zero. And now I can take the second derivative, g prime prime of x is going to be equal to three times negative four is negative 12x squared, decrement the exponent, plus 12. And so let's see, where could this be undefined? Well, the second derivative is just a quadratic expression here which would be defined for any x, so it's not gonna be undefined anywhere. So interesting points where we could transition from going from a negative to a positive or a positive to a negative second derivative is where this thing could be equal to zero. So let's figure that out. So let's figure out where negative 12x plus 12 could be equal to zero.
