Answer

$$ y=\frac{4x}{3-2x} $$ We find that: Asymptotic: $y=-2$ and $x=\frac{3}{2}$ $x$-intercept: 0 $y$ -intercept: 0

Work Step by Step

$$ y=\frac{4x}{3-2x} $$ The function is undefined for $x=\frac{3}{2}$, so the line $x=\frac{3}{2}$ is a vertical asymptotic.. To find a horizontal asymptotic, let $x$ get larger and larger, so that $$ y=\lim _{x \rightarrow \infty} \frac{4x}{3-2x}=-2 $$ This means that the line $y=-2 $ is a horizontal asymptotic. When $x=0 $ the $y$-intercept is 0 When $y=0 $ the $x$-intercept is 0 So, Asymptotic: $y=-2$ and $x=\frac{3}{2}$ $x$-intercept: 0 $y$ -intercept: 0
