8. if a and b are non-empty sets we define their cartesian product a x b as follows: a, b) a e a and b e b that is, ax b is the set of all ordered pairs with elements of a in the first slot and elements of b in the second slot produce a function f : n x n n which is injective.

answer: median

step-by-step explanation:

the median is the middle value when a data set is ordered from least to greatest

definitely a. the others have almost all data points on one side of the line.

step-by-step explanation:

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph

70.30
