Given the expression:
[tex]y=9^x[/tex]
The graph of the function will be as shown in the following picture:
We will study the behaviour for the following conditions:
x < 0, the function tends to zero
x = 0, the function will be = 1, which represents y-intercept
0 < x < 1 , the function will be in the rangle 1 < y < 9
x = 1 , the function will be = 9
x > 1 , the function tends to infinity
