This actually should be reported. There are no choices. However there are ways of finding out what the zeros are and I will do that first to begin with.
The first is a bit of a cheat. My calculator will do it, so I'm just going to get the answer from it.
x can equal 3 x can be 5 x can be 4
So f(x)= a (x - 3)(x-5 )(x -4) is the basic equation. You need another point other than the zeros to determine the value of a.
Method 2 Get the graph. I've done that below. Basically it agrees with what my calculator says.
Method 3 You could factor it, but simple factoring methods don't work with this question.
Method 4 You could do this in a method similar to a quadratic, but I can't do that. It is on my to do list to lean though.
In a proper volleyball ready position, the knees are bent, the hands are out in front of the player at waist level and just outside the knees, and the player's weight is balanced forward.
