Which graph is not a function

The first graph

Step-by-step explanation:

The first graph is not a function because it just has plotted points, not graph to actually represent it

The other two graphs we would be able to determine the function that makes each one

A function cannot be figured out with only the points in the first graph

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.

if you need just tell me and i will come to the rescue.
