7-10 Function Notation Express the rule in function notation. (For example, the rule "square, then subtract $5^{\prime \prime}$ is expressed
as the function $f(x)=x^{2}-5 . )$
$$\text {Add}1, \text {take the square root, then divide by }6$$
So for this one, we're gonna square that night to so make sure to first have a variable in this case will use X. So we first square. So you do X wearing and you add to and that's a
All right, We are going to take this verbal expression where we subtract one from X and then square, and we're going to write it in function notation. So with this, whenever you subtract one, you must do X minus one and use parentheses to make sure that you know the entire thing is going to be squared. Then you'll add the little exponents of two, and you have exactly that.
All right, we are going to take a verbal expression where X is multiplied by three, then subtracted by five. We are going to write this in function notation, form function notation. It just means f of X. It's a fancy name for why, so that the vex is equal to three times X, then subtract five.
In this question, we have to express the ruling function mutation. Okay, so as we know that a concert is our room and we have to represent punching by taking a letter, let's say effort and even tried to function as FX is. So here X is the number when we apply operation on this number even signed out the function f x or we can say that by applying a new rule off on this number, then you even get the function f x. Okay. Now involved were form on in L. A radical form. It is expressed the room as I'm just taking an example here like this, uh, Esquire. The number then So this is the end typical form to apply the room on the function and in numerical form, we can write it as a quarter number X year. We have to square. The numbers will be equal to X squared. Then we have to add in this moment it will be quicker plus two. So the function we've been in the performance it's a script must now coming to the question. Similarly, we have to apply this method as we can take the function F X Okay. No, What we do is we first had to add one in them giving number. So as we have to begin the numbers extreme Foster fall in the function. Okay? I'm just taking it step by step. You most of all, we have to add one. So I relied one in the number X so even give them service explains one. Okay, Now, in the next step, what today is I'll take the Squire mood so we can write it as f X. Oh is equality. We have to take a squired him from the previous function. So it will be as on the ruled X plus one. Yes. No. In the next to step, we have to divide by six. That means the previous function has to divide by six. So the function affects will be equal to as on the road X plus one divide by 60. So this is the required solution for the function notation. Or we can say that before this required cushion Okay, so fx will be called on the road X plus one up on six
