Hello all, I am having some difficulties with a question. Hope you guys can help shine some light on the situation.(adsbygoogle = window.adsbygoogle || []).push({});

Use the triangle Inequality and the fact that 0< |a| < |b| + => 1/|b| <

1/|a| to establish the following chains of inequalities.

|x-2 / x^2+9| "Is less than and equal to" |x| + 2 / 9

Sorry about the display of the question, I really dont know other way to correctly type it.

Please explain your answers, and the reason you use such method to answer this question.

Thanks alot for your much needed help.
