x    y-values

1    175

2   175

3   225

4    275

The domain is 1,2,3,4  it would be from 1 to 4 if the electrician bills for partial hours, or greater than 4, but this is not in the chart.

The range is 175,225,275.  Again there could be other values in between or greater than 275, but it is not in the chart.

Step-by-step explanation:  It is a function because for each x-value there is only one y-value, even if the y-value is the same for two of the x-valus

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.

step-by-step explanation:
