Is It a Function Tables

Which value of w would allow these coordinates to represent a function?

• -3

• -5

• 6

• 0

This mapping does not represent a function.

Why not?

• Because two inputs (-3 & -2) result in the same output (7)

• Because one of the inputs (-3) can result in two outputs (5 & 6)

• Because the arrows don't cross

• Because the inputs are negative put the outputs are positive
