A function has that for every x, there is a different y value.
In the equation 3x+8=y, it's pretty clear that 2 different x values can create the same y value.
You can also graph it in desmos to see.
So, 3x+8=y is a function. :))

I think, when you said "In the equation 3x+8=y, it's pretty clear that 2 different x values can create the same y value.", you meant "In the equation 3x+8=y, it's pretty clear that 2 different x values CANNOT create the same y value."
