Answer: it is the first function: y = f(x) =
log_9x


Step-by-step explanation:

1) You can give a quick answer to this question when you realize that the function graphed is restricted ot positve x - values.

Because, the domain of both 9ˣ and x⁹ is all the real numbers and, indeed, the domain of the logarithmic function is x > 0.

2) Other remarkable feature is the limit of the function as x approaches zero.

The limit of 9ˣ when x approaches 0 is 1.

The limit of x⁹ when x approaches 0 is 0

And the limit of log₉ x when x approaches 0⁺ is negative infinity.
