Final answer:
The line of symmetry for a function and its inverse when graphed is the y-axis.
Step-by-step explanation:
The line of symmetry for a function and its inverse when graphed is the y-axis.
The line of symmetry is a vertical line that divides the graph into two equal halves, reflecting each point across the line. When a function is graphed, the line of symmetry is the y-axis. When the inverse of the function is graphed, the line of symmetry is still the y-axis.
For example, if the original function has a point (2, 3), its reflection across the y-axis would be (-2, 3) on the graph of the inverse function.
