Given $f(x)=\frac{4x-5}{2x-3}$.  

1. Write $f(x)$ in the form $y=k+\frac{a}{2x-3}$.

   Step (a):

   $\frac{2(2x-3)+?}{2x-3}$

2. State all of the asymptotes in the graph.

   Hint (b):

   The vertical asymptote is the value of $x$ that causes division by $0$.
   The horizontal asymptote is $y=k$.

3. Find $\lim\limits_ { x \rightarrow - \infty } f ( x )$.

   Hint (c):

   This is the horizontal asymptote.

4. $\lim\limits_ { x \rightarrow 1.5 ^ { + } } f ( x )$.

   Hint (d):

   Remember to approach $x=1.5$ from the right.
