A.) yes
B.) No

Answer 3

If you can have 2 different y's for the same x, it is not a function.
So what do you think?

Answer 4

What is y when x = 1?

Answer 5

You have a function if, for each value of x there is at most 1 value for y.

Answer 6

a function is something that for any input (something you put in), you get exactly one output (something you take out)

if you put in x = 1, you get either -2 or -3. you are putting in 1 thing (x = 1) and getting two things out (y = -2 or y = -3)

therefore not a function
