Ejemplo recta tipo de intervalo abierto

Intervalo abierto

Se representa mediante una expresión del tipo a < x < b ó (a;b). Por ejemplo, si tenemos el intervalo abierto (1;5), tendremos el conjunto de números mayores a 1 y menores que 5. Sin incluir el 1 y el 5. Representación en la recta real del intervalo abierto (a;b).

Step-by-step explanation:

b) well because you get well

c

step-by-step explanation:

there is vertical asymptote at x = 2 and x = 0

vertical asymptote occurs at the points where the denominator is 0. so we can say that

x = 2 occurs when there is a factor (x-2) in the denominator, and

x = 0 occurs when there is a factor "x" in the denominator

thus, the denominator of the equation would have "x * (x-2)", this is option c only. that's the correct answer.
