Is a persons age a function of his or her height?

a. yes, everyone withe the same age has the same height.

b. yes, for each height, there are people of different ages.

c. no, for each height, there are people of different ages.

d. no, everyone with the same height is the same age.

c. No, for each height, there are people of different ages.

Step-by-step explanation:

We say that y is a function of x when there is a relationship between x and y. For example, the distance you run on a single day and your average speed.

However

There is no relationship between age and height. For example, we may both be the same age and have very different heights.

So the correct answer is:

c. No, for each height, there are people of different ages.

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.
