This reality needs to be reported. There are No options. However, there are ways to find out what the zeros and I'm going to make the first, to begin with. The first is a bit of a cheat. My calculator is going to do it, so I'm going to get the response from it. x can be equal to 3x can be 5x may be 4So f(x)= a (x - 3)(x-5 )(x -4) is the basic equation. You need another different point of the zeros to determine the value of a.Method 2Get the chart. What I have done below. Basically agree with what my calculator says.Method 3You may factor, but simple factoring methods do not work with this question.Method 4 you could do this in a similar method to a quadratic equation, but I can't do that. It is on my to do list to read, though.
