How do you find the zeros of a function
WebThe zeros of a polynomial are the values of x for which the value of the polynomial is zero. To find the zeros of a polynomial that cannot be easily factored, we first equate the polynomial to 0. WebTherefore, the zeros of the function f ( x) = x 2 – 8 x – 9 are –1 and 9. This means f (–1) = 0 and f (9) = 0 If a polynomial function with integer coefficients has real zeros, then they are either rational or irrational values. Rational zeros can be found by …

WebIn various areas of mathematics, the zero set of a function is the set of all its zeros. More precisely, if f : X → R {\displaystyle f:X\to \mathbb {R} } is a real-valued function (or, more generally, a function taking values in some additive group ), its zero set is f − 1 ( 0 ) {\displaystyle f^{-1}(0)} , the inverse image of { 0 ... WebJan 27, 2015 · A zero of a function is an interception between the function itself and the X-axis.
