Answer:
Choice A is correct
Step-by-step explanation:
A function is said to be increasing over a given interval if the value of the function is itself increasing over the said interval. From the graph, as we move from x =0 to infinity the value of y is constantly increasing. Lastly, the point 0 is inclusive in this interval since it lies on the graph while infinity is not inclusive. Therefore, we use square brackets on the left.
Answer:
A. [0,∞).
Step-by-step explanation:
As you see from the graph the minimum value of the function occurs when x = 0 and to the right of this point the graph is moving upwards - the function is increasing towards a value where x is close to infinity.
So it is option A.
