how find the zeros of a function?
315419
Finding the zero of a function means to find the point (a,0) where the graph of the function and the y-intercept intersect. To find the value of a from the point (a,0) set the function equal to zero and then solve for x.

The zero of a function is any replacement for the variable that will produce an answer of zero. Graphically, the real zero of a function is where the graph of the function crosses the x‐axis; that is, the real zero of a function is the x‐intercept(s) of the graph of the function.

Zeros, roots, and x-intercepts are all names for values that make a function equal to zero. ... Geometrically, zeros, roots, or x-intercepts of a function f(x) are the values of x where the graph of the function f crosses the x-axis.

A real zero of a function is a real number that makes the value of the function equal to zero. A real number, r , is a zero of a function f , if f(r)=0 . Example: f(x)=x2−3x+2. Find x such that f(x)=0 .

Find x so that f ( x) = x 2 – 8 x – 9 = 0. f ( x) can be factored, so begin there. If a polynomial function with integer coefficients has real zeros, then they are either rational or irrational values. Rational zeros can be found by using the rational zero theorem.

The zero of a linear function can be found by replacing the y with zero and then solving for x. Quadratic functions are functions that can be put in the form f(x) = ax2 + bx + c, which is called the standard form. Graphically these graphs are parabolas. The zeros of the function are where the f(x) = 0.

To find zeros of the derivative, look at the graph of the derivative function. The zeros will be the points at which the derivative crosses the x-axis. Using a graphing calculator's trace button, you can find the exact locations of x when the function is 0.

The zero of a function is the point (x, y) on which the graph of the function intersects with the x-axis. The y value of these points will always be equal to zero.
