The domain for the function f(x) = |x + 1| is the set of all real numbers.
The range of the function is the set of positive real numbers.
Given the function f(x) = |x + 1|
f(-4) = |-4 + 1| = | -3| = 3
This means that the number -4 is at a distance of 3 units away from -1 on the number line.
f(2) = |2 + 1| = |3| = 3
This means that the number 2 is at a distance of 3 units away from -1 on the number line.
f(1.5) = |1.5 + 1| = |2.5| = 2.5
This means that the number 1.5 is at a distance of 2.5 units away from -1 on the number line.

Median because there is an outlier (1 million and stuff) that is about 10 times as much as everything else
The answer is 80 you divide 240.00 into 3 and get 80
Answer:
you put the variable first
Step-by-step explanation:
Jamie is correct. the reason is because when you put 7x you dont reverse it because we dont know what to multiply 7 by as when its 7x we know to multiply 7 by x
A) If we assume the service charges are a one-time charge, we can let x represent the number of days of rental and a(x) and b(x) the charges for company A and company B, respectively. We are given the initial value and the rate per day in each case, so we can simply write down the equations:
... a(x) = 15 + 35x
... b(x) = 10 + 42x
B) Company A charges less for any rental lasting 1 day or longer. The total for the 1st day (50 vs 52) is less, and the rate per day is less for company A.
C) The difference in cost is ...
... b(x) - a(x) = (10 +42x) -(15 +35x) = 7x -5
so for 10 days, company A costs 7·10 -5 = 65 dollars less
