Quando Δ < 0 \Delta<0 Δ < 0 , analisando o gráfico de uma função quadrática podemos concluir que:

a parábola não terá pontos de intersecção com o eixo das abscissas.

a parábola terá dois pontos de intersecção com o eixo das abscissas.

a parábola tangenciará o eixo das abscissas.

não existirá gráfico para esta função.

O módulo ou valor absoluto, que é representado por duas barras verticais |a| , é um número real a , em que nesse número é desconsiderado o seu sinal:

|2| = 2 |-2| = 2 |3| = 3 |-3| = 3

|-2| = -2 |-2| = -2 |-3| = -3 |-3| = -3

2 = 2 |-2| = 2 |-3| = -3 -3 = 3

O elemento n de uma sequência representa:
