Strategic Advice: Don't answer this question too quicklyâ€”you may be tempted to substitute 3 for x, but 3 is the output (range), not the input (domain).

Getting to the Answer: The given range value is an output value, so substitute 3 for g(x) and use inverse operations to solve for x, which is the corresponding domain value.

You could also graph the function and find the value of x (the domain value) for which the value of y (the range value) is 3. The point on the graph is (-6, 3).
