How to Find the Zeros of a Function. Three Methods: Finding Zeros by Factoring Finding Zeroes by Using the Quadratic Formula Finding Zeroes by Graphing. The zero of a function is a value of x that makes the value of function equal to zero. You usually try to find the zeros of a function to find an answer to a polynomial equation, such as x 2 + 4x +3 = 0. Follow these steps to learn several different ways how to find the zeros of a function. Ad.
And actually, your question is a very good one. In a strict mathematic sense, y is just a variable. When someone writes y=f(x), it means that the value of y depends on the value of x, which is another variable. That is, for different values of x, there is a function, called f(x), which determines the value of y.
