So I have the function f of x here, and we're defining it using a polynomial expression. And what I would like to do here is take the derivative of our function, which is essentially going to make us take a derivative of this polynomial expression. And we're gonna take the derivative with respect to x. So the first thing I'm gonna do is let's take the derivative of both sides. So we could say the derivative with respect to x of f of x, of f of x, is equal to the derivative with respect to x, the derivative with respect to x, of x to the fifth, x to the fifth, plus two, plus two x to the third, minus x squared. And so the notation, just to get familiar with it, you could view this as the derivative operator. This says, look, I wanna take the derivative of whatever is inside of the parentheses with respect to x.
