Best ResponseYou've already chosen the best response.1(we're not done yet, you still need to plug in your values of f(7), f(3), and simplify)

Best ResponseYou've already chosen the best response.1uh, not quite what is the value of f(7)?

Best ResponseYou've already chosen the best response.1right, now what is the value of f(3)?

Best ResponseYou've already chosen the best response.1Right! so, our formula [f(7)f(3)] / 7(3) gives us (050)/(10)
