Can someone show me how to do this?
Find the inverse of {(3, 2), (4,2)} and tell whether its a function.

Best ResponseYou've already chosen the best response.2Just reverse the x and y values in the ordered pairs. Then check if any of the ordered pairs have the same first number. If they do, it's not a function.

Best ResponseYou've already chosen the best response.2so all you need to do is reverse x and y? what will happen if you have 3 ordered pairs? would you do the same?

Best ResponseYou've already chosen the best response.2Yep. You would do the same. Is the inverse a function or not?

Best ResponseYou've already chosen the best response.2does this rule apply to all functions?

Best ResponseYou've already chosen the best response.2Yes. The 2 is paired with more than 1 y value

Best ResponseYou've already chosen the best response.2Absolutely. learn these lessons about functions well because you will be involved with functions for as long as you study math.
