What's the derivative of negative 7x squared going to be? Well, it's just going to be negative 7 times the derivative of x squared, which is 2x. What is the derivative of 3x going to be? Well, it's just going to be 3 times the derivative of x, or 3 times the derivative of x to the first. The derivative of x to the first is just 1. So this is just going to be plus 3 times, could say 1x to the 0, but that's just 1. And then finally, what's the derivative of a constant going to be?
