Jason's math teacher asked every student in the class to write down how many children live in his/her household. is this an example of a function? why or why not?
a) no, because several students may have the same number of children in their households.
b) yes, because several students may have the same number of children in their households.
c) no, because most students will not have the same number of children in his/her household.
d) yes, because each student will have only one answer for the number of children in his/her household.

D)Yes, because each student will have only one answer for the number of children in his/her household.

Step-by-step explanation:

Jason's math teacher asked every student in the class to write down how many children live in his/her household.

Yes, the following is an example of a function because each student will write just a single value and not two or three or more as the number of children in there household are some number.

( Also Function is a mapping that maps every element of one set to the unique element of the other set).

Hence, the correct answer is:

D)Yes, because each student will have only one answer for the number of children in his/her household.

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
