So everywhere where we see an x in the definition of f of x, we would replace with a g of x. So this is going to be equal to, this is going to be equal to one plus, instead of the input being x, the input is g of x, so the output is one plus g of x. And g of x, of course, is cosine of x. So instead of writing g of x there, I could write cosine of x. And one way to visualize this is I'm putting my x into g of x first. So x goes into the function g, and it outputs g of x. And then we're gonna take that output, g of x, and then input it into f of x, or input it into the function f, I should say.
