Answer:
The correct option is A.
Explanation:
The given graph is a continuous and increasing curve.
The graph of an exponential function is continuous and increasing of decreasing at increasing rate. The given graph increasing at increasing rate therefore the given graph is an absolute function.
The graph of a polynomial function is continuous. It is increases or decreases for different intervals. Therefore the given graph is not a polynomial function.
The graph of an absolute function is a v shaped graph. It is not represented by the curves. Therefore the given graph is not an absolute function.
The graph of step function is a piece wise function or a discontinuous function. Therefore the given graph is not an absolute function.
Therefore the correct option is A.
