# Cubic Graph Sketching

Cubic Graph Sketching start considering the $x$-intercepts and whether the leading coefficient is either positive or negative. Question 1 Sketch the graph of $y=(x-1)(x+2)(x-3)$. The graph cuts at $x=1, x=-2, x=3$. Question 2 Sketch the graph of $y=(x^2-2x)(x+3)$. $y=(x^2-2x)(x+3) = x(x-2)(x+3)$ The graph cuts at \( x=0, […]
