Work Step by Step

$r(x)=\frac{4x+1}{x-2}$, a. Table 1 $\begin{array}{II} x & r(x)\\ 1.5 & -14\\ 1.9 & -86\\ 1.99 & -896\\ 1.999 & -8996 \end{array}$ Table 2 $\begin{array}{II} x & r(x)\\ 2.5 & 22\\ 2.1 & 94\\ 2.01 & 904\\ 2.001 & 9004 \end{array}$ Table 3 $\begin{array}{II} x & r(x)\\ 10 & 5.125\\ 50 & 4.1875\\ 100 & 4.0918\\ 1000 & 4.009018 \end{array}$ Table 4 $\begin{array}{II} x & r(x)\\ -10 & 3.25\\ -50 & 3.8269\\ -100 & 3.91176\\ -1000 & 3.99101796 \end{array}$ b. - As $x$ approaches $2^{-}$ from the left(Table 1), $f(x)$ approaches $-\infty$ - As $x$ approaches $2^{+}$ from the right(Table 2), $f(x)$ approaches $\infty$ c. - As $x$ approaches $\infty$ (Table 3), $f(x)$ approaches $4^{+}$ from the right - As $x$ approaches $-\infty$ (Table 4), $f(x)$ approaches $4^{-}$ from the left The horizontal asymptote is $y=4$.
