13. Which of these can be represented as a function? INPUT………………………………………OUTPUT
a) Every basketball player on a team has a unique jersey number

b) Every licensed driver has one driver’s license number

c) Every email receiver has one email address

(There is no picture for this and this is all the information I was given. )

you can't solve x because it is 2 linear equation and you only have one equation

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
