What is the domain of the function?all real numbers✔ x > 0x < 0
What is the inverse of the logarithmic function f(x) = log9x?
How can you use a point on the graph of f –1(x) = 9x to determine a point on the graph of f(x) = log9x?✔ Switch the x- and y-coordinates.Use the opposites of the x- and y-coordinates.Use the reciprocals of the x- and y-coordinates.

The graph shows a logarithmic function f. What do f and the function g(x) = log6x have in common? Select all that apply.
What are the domain and range of the logarithmic function f(x) = log7x? Use the inverse function to justify your answers.
The inverse of the logarithmic function f(x) = log7(x) is the exponential function g(x) = 7^x. For the exponential function g(x) = 7^x, the domain is all real numbers (-∞, ∞) and the range is all positive real numbers (0, ∞). Because the domain of a function is the range of its inverse, and the range of a function is the domain of its inverse, the domain of f(x) = log7(x) is all positive real numbers (x > 0) and the range is all real numbers (-∞, ∞).
