Now, the derivative of a number, or I guess you could say a scaling factor, times a function. The derivative of a scalar times a function is the same thing as the scalar times the derivative of the function. What does that mean? Well, that just means that this first term right over here, that's going to be equivalent to 3 times the derivative with respect to x of f of x plus this part over here is the same thing as 2. Let me make sure I don't run out of space here. Plus 2 times the derivative with respect to x of g of x. So the derivative of h with respect to x is equal to 3 times the derivative of f with respect to x plus 2 times the derivative of g with respect to x.
