i answered these problems but got them wrong and don't know why.
1) \(\displaystyle lim_x\rightarrow-\infty\) \(\displaystyle \frac {\sqrt{7+2x^4}} {3x+x^2}\)
i got \(\displaystyle +\infty\)
2) \(\displaystyle lim_x\rightarrow9^-\) \(\displaystyle \frac{9-x}{3-\sqrt{x}}\)
i got 6
3) \(\displaystyle lim_x\rightarrow-3^-\) \(\displaystyle \frac{-x}{x+3}\)
i have know idea how to do this one
