Question

I Need help with this urgently.........

Answer 1

A. [0,∞).

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.

Answer 2

Choice A is correct

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.
