Question

6. Does the set of ordered

pairs represent a function?
Explain.
{(0,5), (-2, -1), (0, -5), (3, 20)}

Answer 1

Answer: this is not a function because the X values are repeating for example we see that 0 is set in the X value side it can’t have 5 and -5 as it’s y at the same time therefor it’s not a function
