So we're given this function over here more asked to, um express the given function age of the composition of two functions F N g. So that each of X is equal effort. You vics. So we want h of x Toby expressed of the composition of two functions such that h of x is equal f of X half of geophysics. Basically, we want to find ah, function. That's gonna be the what? I did it again. Sorry, it's gonna we're looking for and f of gox and so basically won't want a function that's considered the outdoor function, after which we can put this inter function. And we want this over here, this whole h of X to be equal to this thing over here. And so let's let's look at this function What can be the input to the function? If you think about it, it makes sense that two X minus five is the input to this function. Or actually scratch that. Let's talk about what the outer function will be. The outer function is gonna be your f It's gonna be what your input goes into. And just by looking at this, we can see that our outer function f of X is going to be eggs is going to be X cubed. Any makes sense because this X over year is gonna be where our import get substituted, which is the case here. So if this is our outer function, our inner function, it's only logical if our inter function is this thing over here. Two x minus five. So now if we do f of g of X, basically, wherever I see an X in my half of its function, I'm replacing it with the G of X, so it's gonna be equal the two x minus five cube. Um, it's it's kind of tricky efforts, but you just have to recognize that whenever you have these kind of functions, like, say, you have some expression year to the end power, always when and if you want to express as a composition, always treat this outer function like X to the end as your um as your f of X or as your outer functions heart and the expression is always going to be your inner function or G of X. So it's kind of tricky at first, but you should have to learn to recognize what the outer function will be and what the inter function will be. And so I hope that stuff.
