I thought I was right here - I chose these answers because A. When you square root the y^3 it gives the answer to be + or - so it's not a function, same thing with B.

The last two, I did the math and it gave me a y input value. So I decided they were functions.

However it told me I was incorrect. At least one of them is wrong but I'm not sure which one - anyone help?

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

i hope this and i hope you get it right. it took me a while to get this done for you. : )
