Algebra and Trigonometry 10th Edition

$f(x)=-\frac{2x-1}{x-2}$ matches the graph labeled (a)
The vertical asymptote is: $x-2=0$ $x=2$ The x-intercept: $f(x)=-\frac{2x-1}{x-2}=0$. $2x-1=0$ $x=\frac{1}{2}$ The graph passes through $(\frac{1}{2},0)$ The degree of the denominator is equal to the degree of the numerator. The horizontal asymptote is the ratio of the leading coefficients: $y=\frac{-2}{1}=-2$
