Which table represents a function?

step-by-step explanation: to determine what table represents a function, remember that a function is a relation in which each x-term corresponds to exactly one y-term.

when we have a table like this, we can translate the table into a list of ordered pairs to see it easier.

the ordered pairs are list in black in the image provided.

notice that each x-term has exactly one y-term and means that the first table is a function.

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75
