what is the relationship between the zeros and the equation of your function?
2907
A zero is the location where a polynomial intersects the x-axis. These locations are called zeros because the y-values of these locations are always equal to zero. A factor is one of the linear expressions of a single-variable polynomial. A polynomial can have several factors, such as the factors...

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.

A zero of a polynomial function is a number that solves the equation f(x) = 0. These numbers are also sometimes referred to as roots or solutions. A rational zero is a rational number, which is a number that can be written as a fraction of two integers.

Actually, the term 0 is itself zero polynomial. It is a constant polynomial whose all the coefficients are equal to 0. For a polynomial, there may be few (one or more) values of the variable for which the polynomial may result in zero. These values are known as zeros of a polynomial.

Roots are also called x-intercepts or zeros. ... By definition, the y-coordinate of points lying on the x-axis is zero. Therefore, to find the roots of a quadratic function, we set f (x) = 0, and solve the equation, ax2 + bx + c = 0.

Algebraically, zeros, roots, or x-intercepts of a function f(x) are the values of x that make the statement f(x) = 0 true. 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.

Sayani R. *Given a function of the form f(x)=ax2+bx+c , one can find the zeroes of the function (that is, where f(x)=0 ) by using the quadratic formula: x=−b±√b2−4ac2a .

For y = x^2 - 1, the discriminant equals 0 squared - 4 times 1 times -1 or 0 plus 4. The square root of 4 is both plus 2 and minus 2, so that's why this function has two zeros. For y = x^2 + 1, the discriminant equals 0 squared - 4 times 1 times 1 or 0 minus 4.

The zeros of a quadratic equation are the points where the graph of the quadratic equation crosses the x-axis.

In mathematics, a zero (also sometimes called a root) of a real-, complex-, or generally vector-valued function , is a member of the domain of such that vanishes at ; that is, the function attains the value of 0 at , or equivalently, is the solution to the equation .

Root of a polynomial is that value of x that makes the polynomial equal to 0. ... So the difference is: whenever one has a function f : X→R one says that x* is a zero of f if f(x*) = . On the other hand, the same x* is a root of the equation f (x) = .

The zeros of the function are where the f(x) = 0. These functions can have 0, 1, or 2 real zeros. There are several techniques for finding the zeros of a quadratic function, including the square root property, factoring, completing the square, and the quadratic formula.

With the three bar equal sign, f(x) has been defined as zero and it will always be zero. Originally Answered: What is the difference between f(x) ≡0 and f(x) =0? The first symbol means that f(x) is the zero function. The second means there is at least one value of x whereby f maps x to 0.
