yes
no

Explain to me please

Answer 1

Take a vertical line (like a ruler or a book)

Answer 2

and drag it through the entire graph

Answer 3

Are there any points where this vertical line cuts through the graph more than once?

Answer 4

no. so it's yes

Answer 5

you are correct, it is indeed a function since it passes the vertical line test

Answer 6

If there were any x values that produced more than one y value (which would make it fail the vertical line test), then it wouldn't be a function
