So it's gonna take the cosine. Now, its input is w of u of x. We already figured out w of u of x is going to be this business. So it's going to be sine of x plus one. Where the u of x is sine of x, but then we inputted that into w, so we got sine of x plus one. And then we inputted that into h to get cosine of that, which is our original expression, which is equal to g of x. So the whole point here is to appreciate how to recognize compositions of functions.
