For an exponential function in the form of y=ab^x, if b is between 0 and 1, what happens to the graph of the function as x increases?
a.
the graph gets closer to the x-axis.
b.
the graph gets closer to the y-axis.
c.
the graph curves up away from the x-axis.
d.
the graph curves down away from the x-axis.

A.

The graph gets closer to the x-axis.

Step-by-step explanation:

We are given an exponential function:

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. tends to zero

Hence, tends to zero

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

Hence, A is the correct option
