Micah is running a sports trivia contest the entrance fee is $20 the winner will get $500 micah keeps what is left over after paying the winner the function f(x)=20x-500 describes how much money micah earns if x people enter the contest what does the inverse function f^-1(x) describe

Given: The entrance fee in contest = $20 and

Winner prize amount = $500.

Also what is left over after paying the winner the function :

f(x) = 20x-500, describes how much money Micah earns if x people enter the contest.

Solution: Let us find inverse function first.

Writing given function in terms of y.

y = 20x-500

Switching x and y, we get

x = 20y -500.

Now, solving it for y, we get

x +500 = 20y

.

actually, no it isn't. when i was in junior high school, it was a blast. considering that it was a pre international baccalaureate school.
