## Cubic graphs
-$$y=a(x-b)^3 + c$$
+$$y=a(bx-h)^3 + c$$
-- $m=0$ at *stationary point of inflection*
+- $m=0$ at *stationary point of inflection* (i.e. ({h \over b}, k)$)
- in form $y=(x-a)^2(x-b)$, local max at $x=a$, local min at $x=b$
- in form $y=a(x-b)(x-c)(x-d)$: $x$-intercepts at $b, c, d$
-
+- in form $y=a(x-b)^2(x-c)$, touches $x$-axis at $b$, intercept at $c$
## Quartic graphs
- Generate two new equations with only two variables
- Rearrange & solve
- Substitute one variable into another equation to find another variable
