Question

Efetue a soma e diferença de monômios

x²-2x+4

4x³-4-2x³-2

x²-4x²+x²

-x⁵-b+ 4x⁵+b

-5x²+2x²+3+3x²
​

Answer 1

x²-2x+4

$\mathrm{Dominio\:de\:}\:x^2-2x+4\:$$\mathrm{Pontos\:de\:interseccao\:com\:o\:eixo\:de}\:x^2-2x+4:\quad \mathrm{Y\:intersepta}:\:\left(0,\:4\right)$

$\mathrm{Vertice\:de}\:x^2-2x+4:\quad \mathrm{Minimo}\space\left(1,\:3\right)$

4x³-4-2x³-2

$4x^3-4-2x^3-2=2x^3-6$

$4x^3-4-2x^3-2$

$2x^3-4-2$

$2x^3-6$

então eu so fiz estes 2 blz eu espero ter te ajudado <3
