So we got a pretty valid response there. Now let's try something where the slope might change. So let's say I have g of x is equal to x squared. The power rule tells us that g prime of x would be equal to what? Well, n is equal to 2, so it's going to be 2 times x to the 2 minus 1. Or it's going to be equal to 2x to the first power, it's going to be equal to 2x. So let's see if this makes reasonable sense.
