Question

repuesta de matematicas dados los polinomios p [x] =4x2-1

Answer 1

$p(x)=4x^2-1 \\ \\ p(x)= (2x-1)(2x+1) \\ \\ \mathrm{Dominio\:de\:}\:(2x-1)(2x+1)\::\quad \begin{bmatrix}\mathrm{Solucion:}\:&\:-\infty \:\ \textless \ x\ \textless \ \infty \\ \:\mathrm{Notacion\:intervalo}&\:\left(-\infty \:,\:\infty \:\right)\end{bmatrix} \\ \\ \mathrm{Rango\:de\:}\left(2x-1\right)\left(2x+1\right):\quad \begin{bmatrix}\mathrm{Solucion:}\:&\:f\left(x\right)\ge \:-1\:\\ \:\mathrm{Notacion\:intervalo}&\:[-1,\:\infty \:)\end{bmatrix}$ 

$\mathrm{X\:intersecta}:\:\left(\frac{1}{2},\:0\right),\:\left(-\frac{1}{2},\:0\right),\:\mathrm{Y\:intersecta}:\:\left(0,\:-1\right)$
