Answer:
EL NIDO
Step-by-step explanation:
[E] { (0, 0), (1, 2), (2, 4) } is a function because each input value leads to only one output value.
[C] { (0, 0), (0, 2), (2, 4) } is not a function because there are two output values for 0 which are 0 and 2.
[L] { (a, 1), (b, 2), (c, 1) } is a function because each input value leads to only one output value.
[N] { (0, -1), (1, 2), (2, 4) } is a function because each input value leads to only one output value.
[O] { (9, b), (9, c), (9, d) } is not a function because there are three output values of 9 which are b, c, and d.
[I] { (Palawan, Mimaropa), (Romblon, Mimaropa)} is a function because each input value leads to only one output value.
[D] The graph shows a function because there is only one y value for each x value.
[R] The graph does not show a function because there could be two y values when given one x value.
[O] The graph shows a function because there are multiple input values (x) and only one output value (y) and rules only say that it is not a function when there multiple output values.
