Answer :
Y=11 is a function, because a function is a set of numbers where for you only have one input for every output. In this case it is a one kt one function because there is only one output for every input. Every input results in 11, therefore this is a function.
y = 11 is a function since it has both an input value which is 11, and an output variable y
For us to have a function, there must be both an input and output variable or constant.
The expression y = c is a function since we have an input value c and an output value y.
We can say that y is equal to c for every value of the input variable c.
Given the expression y = 11, we can therefore conclude that it is a function since it has both an input value which is 11, and an output variable y
