How do you find the limit of # (3 x^4 + 4) / ((x^2 - 7)(4 x^2 - 1)) # as x approaches infinity?

KengaRu [80]

$\displaystyle\lim_{x\to\infty}\frac{3x^4+4}{(x^2-7)(4x^2-1)}$

Expanding the denominator gives

$(x^2-7)(4x^2-1)=4x^4-29x^2+7$

Then in the whole rational expression, we can divide through by $x^4$ . Since $x\to\infty$ , we assume that $x>0$ , so this is legal.

$\dfrac{3x^4+4}{4x^4-29x^2+7}=\dfrac{3+\frac4{x^4}}{4-\dfrac{29}{x^2}+\dfrac7{x^4}}$

As $x$ gets arbitrarily large, the rational terms in the numerator and denominator become negligible. So for large $x$ , we have

$\dfrac{3x^4+4}{(x^2-7)(4x^2-1)}\approx\dfrac34$

And so the limit is $\dfrac34$ .

Answer:

Some ages that Mark could possibly be are...

16, 17, 18, 19, and 20. I found my answers because to have a job or work at a program, you have to be at <em>least</em> 16. So Mark could be 16, 17, 18, 19, or 20. He would be able to work being 21 because that is the drinking age and you are already in the adult stage and you are old enough to be responsible with what you do.
