Limit of a Two-Dimensional Function with Positive Inputs: Solving for -1/5

[tt2348]

Homework Statement

$\lim _{ (x,y)\rightarrow (0^{ + },0^{ + }) }{ \frac { { e }^{ \sqrt { x+y } } }{ 4x+2y-5 } }$

Homework Equations

eh.

SO I did the problem. I usually sub 1/n for 0+ in most of these, but clearly the top goes to 1 from +inf, and the bottom goes to -5... Hence... -1/5

But.
The multiple choice was

A)$\stackrel{\nearrow}{\rightarrow}\frac {1 }{ 5 }$

B) $\frac {1 }{ 5 }$


C)$\stackrel{\nearrow}{\rightarrow}1$

D) 1

What on Earth does $\stackrel{\nearrow}{\rightarrow}$ mean?!??

Nothing wrong with what you did. I have no idea what they are trying to say.
