Now that we can find rational zeros for a polynomial function, we will look at a theorem that discusses the number of complex zeros of a polynomial function. The Fundamental Theorem of Algebra tells us that every polynomial function has at least one complex zero. This theorem forms the ...
Enter the given function in the expression tab of the Zeros Calculator to find the zeros of the function. This is a polynomial function of degree 4. Therefore, it has four roots. All the roots lie in the complex plane. The roots of the function are given as: ...
Use a graphing calculator to find the zeros of the function {eq}f(x)=2x^{4} + x^{3} - 4x^{2} +x+2 {/eq}. Step 1:On a graphing calculator, press [y=]. Step 2:Enter the polynomial at the prompt "Y1= {eq}2x^{4} + x^{3} - 4x^{2} + x + 2 {/eq}". ...
When the function is a lower order polynomial such as a linear or quadratic, a graphing calculator is not necessary. The zeros of these functions be easily found without one. For example, f(x) = 2x+1 is a linear function. You can find the zero of this function by substituting f(x) ...
