There is only one solution.

y = x+2

x = -1

Substitute x = -1 in y = x+2

y=-1+2

y = 1

We only get the single value of y and x so It's clear that there's only one solution.

You are to demonstrate that you understand what represents a function and what does not represent a function. You may do this by

My name is Ann [436]

We know that functions are mathematical entities that assign unique outputs to given inputs. In other words, a function can't have repeated values in the input repeated x-value.

For example consider the relation {(1,4), (1,5), (2,6), (3,7), (4,8), (5,9)}.

We see that above relation has repeated x-value "1" which is assigned to two different output values 4 and 5. So by definition of function, above relation can't be a function.
