Answer 3

Find the limit of:
\[\lim_{x \rightarrow \infty} (x ^{5}-4x ^{4}-3x+5)\]
I'll post my work shortly.

Answer 4

I figured out my mistake. Here is the solution:

The above equation =
\[\lim_{x \rightarrow \infty} x ^{5}(1-\frac{ 4x ^{4} }{ x^{5} }-\frac{ 3x }{ x ^{5} }+\frac{ 5 }{ x ^{5} })=\lim_{x \rightarrow \infty}x ^{5}(1-\frac{ 4 }{ x }-\frac{ 3 }{ x ^{4} }+\frac{ 5 }{ x ^{5}) }=\lim_{x \rightarrow \infty}x ^{5}(1-0-0+0)=\]
\[\lim_{x \rightarrow \infty}x ^{5}(1) = \lim_{x \rightarrow \infty}x ^{5}=+\infty\]
