Question

Is the relation shown in the arrow diagram a function?

Answer 1

It's not C

Remember
"If each x value has one y value, it is a function"

Answer 2

You can eliminate C and D bc there is an equal amount of domains to ranges

Functions
Domain = Range - YES
Domain > Range -YES
Domain < Range - YES

Answer 3

And then you can eliminate the second one, because in order for a function to be a function, in needs to pass the vertical line test, so each x needs to have it's own y
So, the second one is wrong


What does that leave you with
