1. (I)Graphs of the Form y f x
The graph of y f x can be sketched by first drawing y f x
and noticing;
f x is only defined if f x 0
3. (I)Graphs of the Form y f x
The graph of y f x can be sketched by first drawing y f x
and noticing;
f x is only defined if f x 0
f x 0 for all x in the domain
f x f x if f x 1 and f x f x if f x 1
5. (I)Graphs of the Form y f x
The graph of y f x can be sketched by first drawing y f x
and noticing;
f x is only defined if f x 0
f x 0 for all x in the domain
f x f x if f x 1 and f x f x if f x 1
dy f x
implies;
dx f x
stationary points must still be stationary points
there are critical points where f x 0
