Answer:
d. x ≥ 2 or x ≤ -2
Step-by-step explanation:
The domain is the set of all possible x-values that will make the function work.
For the function to work, the radicand cannot be negative.
x² - 4 ≥ 0
x² ≥ 4
x ≥ 2 -x ≥ 2
x ≤ -2
The domain is x ≥ 2 and x ≤ -2.
The graph of your function shows that ƒ(x) does not exist when -2 < x < 2.
Answer:
=IF(A1<40000,(18%*I18),(27%*A1))
Step-by-step explanation:
The spreadsheet expression to be used is the "IF" function. The "IF" function is one that returns a value based on the conditions stated thereafter in the spreadsheet formula. Like every spreadsheet function, this also starts with =
In the question given,
The value to be examined is in cell A1. if A1 is less than $40000 is written as A1<40000, is true, the spreadsheets executes the next function stated as (18%*I18) otherwise (which in this case can be interpreted as A1 greater than or equal to $40000), compute the next command as shown above; (27%*A1)
The final parenthesis closes the command.
Hence the expression is IF(A1<40000,(18%*I18),(27%*A1)).
Good luck on this it's pretty easy

Answer:
The waiter earns $7 per hour
Step-by-step explanation:
In this question, we are asked to calculate the amount a waiter earns per hour at work given the total he had earned including tips.
To solve this question, we can see that we have been given the total amount he has earned and also the amount he has also earned in tips.
Now, to get the standard amount he’s supposed to earn per hour, firstly, we have to subtract the amount he has earned in tips from the total. Mathematically that is 128-86 = $42
This means, by standard he has earned $42 in six hours. Now, we need to calculate the amount she earns by hour.
To do this, we simply divide the total amount earned by the number of hours.
Mathematically that is $42/6 hours = $7 per hour
