I need help figuring out if this is a function or not and why

4) is a function 5) is not a function

Step-by-step explanation:

4) This is a function because even tho some numbers in the domain have the same y value that doesnt mean the x values overlap. THink of it graphically or draw points do the points overlap? It shouldn't unlike question 5!

5) This is NOT a function. Why??? This is because now all numbers except 4 have more than one y value for one x value

for example: 1 has -1 and 3

That would overlap!!

gmt is 4 hrs ahead of edt so just add four hours to 1: 14: 20 (minutes and seconds stay the same)

gmt is 5: 14: 20

hope this !

twenty-six miles over two gallons because the proportion for the original 13 miles to one gallon would be written 13/1 and, doing the same thing to the top and bottom, i multiplied by 2 and got 26/2
