The function above is only true for exactly one x value, so B is your answer.

Notice that the output of the function is y=7. This means that there is one x value that will make this equation true. If there were multiple x values that made it true, the output would simply be just y. When there is a specific output, you can solve for x and figure out that there is one output for that input.
