Lim
x→∞ [itex]\frac{7x^2-14x+7}{\sqrt{2x^4-4x^3+x+7}}[/itex]
Normally wouldn't have an issue here, just slightly confused by the sqrt.
Attempted solution:
[itex]\frac{7x^2-14x+7}{\sqrt{2x^4-4x^3+x+7}}*\frac{x^-2}{x^-2}[/itex]
Yields [itex]\frac{7}{\sqrt{2}}[/itex]
Is this correct?
Similarly:
lim
x→-∞
[itex]\frac{x^3+x+1}{\sqrt{2x^6+x^3+x+3}}[/itex]
Yields [itex]\frac{1}{\sqrt{2}}[/itex]
and
lim
x→-∞
[itex]\frac{x^2+x+1}{\sqrt{2x^4+x^3+x+3}}[/itex]
Yields [itex]\frac{1}{\sqrt{2}}[/itex]
