Factor first. Then, identify the excluded values, simplify, find the x-intercepts, vertical
asympotes, holes in the graph (including the y-value of the hole as well), y-intercept, and
horizontal asymptote.

.

y=\frac{x^3-4x^2+3x}{3x^2-12x}

y=\frac{x\left(x^2-4x+3\right)}{3x\left(x-4\right)}

y=\frac{x\left(\left(x^2-x\right)+\left(-3x+3\right)\right)}{3x\left(x-4\right)}

y=\frac{x\left(x\left(x-1\right)-3\left(x-1\right)\right)}{3x\left(x-4\right)}

y=\frac{x\left(\left(x-1\right)\left(x-3\right)\right)}{3x\left(x-4\right)}

y=\frac{x\left(x-1\right)\left(x-3\right)}{3x\left(x-4\right)}
