Is the following relation a function?
yes or no question

Yes because the the x value is not repeated. It can not be a function if the arrow in one of the x values is pointing to more than one y value.

Hope this helps :)

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
