An inverse function will also qualify as a function if the original is a One-to-One function. This means that each y value corresponds to exactly one x value, thus ensuring that the inverse remains a function.
The function shown in option C meets this criteria, as all x values and y values are distinct. Therefore, the inverse of the function in option C will also be a functional relation.
In contrast, other options have repeated y values, indicating they do not exhibit the one-to-one characteristic.
Hence, the correct answer is option C
700,000 * 45%
700,000 *.45 = 315,000
Final audience is 315,000
