Notes:
How to inversigate a fucntion
1. Accurate sketch of graph either by hand or by calculator.
2. Write Domain and Range in interval notation.
3. Label x and y Intercepts on graph
4. Lable any vertex of write equation of any asymptote.
Example:
1.
Domain: (-∞,∞)
Range: [-11,∞)
Vertex is located at (x,y) where X=-b/2a, Y=f(-b/2a)
X=(3/2)=1.5 Y=-102.25
2.
Domain: (-∞,∞)
Range: (1.∞)
Y-intercept: (0,1)
Asymptote: Y=1
