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.
The function has a minimum value at x = a if f '(a) = 0 and f ''(a) = a positive number. The function has a maximum value at x = a if f '(a) = 0 and f ''(a) = a negative number. In the case of the maximum, the slope of the tangent is decreasing -- it is going from positive to negative.t x = 1 there is a maximum of y = 17. At x = â2 there is a minimum of y = â10. c) y = 2 x 3 + 3 x 2 + 12 x â 4. Since f ' (x) = 0 has no real solutions, there are no extreme values. d) y = 3 x 4 â 4 x 3 â 12 x 2 + 2. At x = 0 there is a maximum of y = 2.
