Question

Evaluate the following limit

Answer 1

\[\lim_{x \rightarrow ?}\frac{ \sqrt{5 + 9x^2} }{ 7 + 2x }\]

Answer 2

approaches infinity

Answer 3

3/2 ???

Answer 4

how do you get that answer?

Answer 5

wait, it is because the '9' and '2' are the only important numbers or largest numbers?

Answer 6

\[\lim_{x \rightarrow \inf}\frac{ \sqrt{5 + 9x^2} }{ 7 + 2x } = \lim_{x \rightarrow \inf}\frac{ \sqrt{5 + 9x^2} }{\sqrt{(7+2x)^2}} \]
