If you can't seem to solve for x, then try graphing the function to find the range.
What does a log function look like?
The logarithmic function may look like the graph below. The negative in front of the function reflects the function over the x-axis, but all other properties of the logarithmic function hold. Here, as a decreases, the magnitude of a increases. As this happens, the graph decreases at a quicker rate as x increases.

What is a domain and range function?
Domain and Range. The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.
