What is the domain and range of this graph

domain: -infinity <\= × >\= +infinity

Range: -infinity <\= y >\= +infinity

Step-by-step explanation:the arrow at the end of the line means it is continuing infinitely in that direction, so the the line is always increasing and decreasing in y and x values.

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:

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
