Answer:
The first one: f(x) = 2
Step-by-step explanation:
In this case, we can see that for ALL values of 'x' the value of y=f(x) doesn't change, it's the same. That's why the function represented by the graph is f(x) = 2.
f(x) =2
Looking at the graph, the value of y does not change. y always equals 2
y=2
Since this is in function notation
