Question

i need some help with this question please!

Evaluate the limit

Answer 1

limit as x extends to -infinity \[3x/(\sqrt(4x^2+10))\]

Answer 2

\[\lim_{x\to-\infty}{3x\over\sqrt{4x^2+10}}\]right?

Answer 3

if so, divide top and bottom by x, then take the limit (careful with the square root sign)
remember that the square root is positive, and the top will tend to negative infinity, so that will tell you the sign of the answer
