Answer
1) This function to the left is a constant function.
2) The asymptote of this function to the left is y = 2.
Step-by-step explanation
1) A function can be increasing, decreasing, constant or some other type of function.
But this function to the left shown on the graph is totally constant and stayed on y = 2. So, this function to the left is a constant function.
2) Asymptote of a function refers to the boundaries of the curve. So, the boundary of this function on the left hand side is at y = 2.
