Answer:
21
Step-by-step explanation:
You were close to de answer but you rounded in a wrong way
If we calculate <em>
</em>we get<em> 21.2602916255</em>
We need to round to the nearest whole number, it means that we have we only have two options: 21 or 22
We need to remember the rounding rules:
- If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up
- If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down
We see that 1 is followed by 2, it means that we have to round the number down, so our answer is 21

Step-by-step explanation:
Given function

We need to find
value corresponding to each
value.
So, plug each
value in equation we get,

Now in next part of question it ask us to check each ordered pair.
Let us plug each
value and
value in the function 

we can see ordered pair
true for function 
Answer:
all real numbers expect 1.
Step-by-step explanation: This is a rational function. when we usually the find the domain of a rational function we would look at the bottom because you don't want the denomonatior to be zero because dividing by zero in math makes the range undefined. so we use the equation and set it up to zero to find the domain. 1-x=0 -x=-1, divide by -1 and we get 1. So x can be any numbers expect 1. Interval notation: (-∞,1)∪(1,+∞)
