The graph gets closer to the x-axis.

Answer:

A.

The graph gets closer to the x-axis.

Step-by-step explanation:

We are given an exponential function:

[tex]y= ab^x[/tex]

Now we know that if a number lies between 0 and 1 and as we keep on increasing its power the number goes on decreasing and ultimately it tends to zero

Here, b lies between 0 and 1 so, as we keep on increasing the power of b it will tend to zero

i.e. [tex]b^x[/tex] tends to zero

Hence, [tex]y=ab^x[/tex] tends to zero

i.e.  The graph gets closer to the x-axis.

Hence, A is the correct option
