Well, for x is equal to 2, g prime of 2, or sorry, for x is equal to negative 2, g prime of negative 2 is equal to 2 times negative 2, which is equal to negative 4. So this is claiming that the slope at this point, so this right over here is negative 4, saying that the slope of this point is negative 4. m is equal to negative 4. That looks about right. It's a fairly steep negative slope. Now, what happens if you go right over here when x is equal to 0? Well, our derivative, if you say g prime of 0, is telling us that the slope of our original function g at x is equal to 0 is 2 times 0 is 0. Well, does that make sense?
