If the following defines a one-to-one function, find its inverse. If not, write "Not one-to-one." \[ \{(2,5),(-8,-35),(-4,-7),(5,-3)\} \] A. $\{(-7,5),(2,-4),(-4,5),(-3,-35)\}$ B. $\{(5,2),(-35,-8),(-7,-4),(-3,5)\}$ C. $\{(-7,5),(2,-4),(-35,-4),(-8,5)\}$ D. Not one-to-one

Step 1 ：The given function is a set of ordered pairs. To find the inverse of a function, we simply switch the x and y coordinates of each pair. This means that the inverse of the function would be \(\{(5,2),(-35,-8),(-7,-4),(-3,5)\}\).

Step 2 ：Let's check if this set matches any of the given options.

Step 3 ：The output matches option B, which is \(\{(5,2),(-35,-8),(-7,-4),(-3,5)\}\). Therefore, this is the inverse of the given function.

Step 4 ：Final Answer: \(\boxed{B. \{(5,2),(-35,-8),(-7,-4),(-3,5)\}}\)
