Which relation is a function? A. https://media.education2020.com/evresources/2003-08-01-00-00_files/i0080000.jpg B. https://media.education2020.com/evresources/2003-08-01-00-00_files/i0080001.jpg C. https://media.education2020.com/evresources/2003-08-01-00-00_files/i0080002.jpg D. https://media.education2020.com/evresources/2003-08-01-00-00_files/i0080003.jpg
Im pretty sure its A.
The coordinates for A are (-3,5) (5,3) (3,-5) (-3,-3) Are there any of the same x values that have different y values?
For it to be a function an X value cannot have anymore than one y value. That being said, A is not correct.
okay
so how would I find it then?
If there is an x value with two different y values, then that isn't a function. Find the one that has no repeating x values with different y values
C
Here are the coordinates for C (2,1) (3,4) (2,-1) (3,-4) Are there any repeating x values with different y values?
yes
so it cant be the same x values
Then it is not a function
Oh its B
Here are the coordinates for B (0,5) (2,5) (1,-4) (2,3) Are there any repeating x values with different y values?
im so blind...
so its d then
yup
thanks
