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

HW: EF Set 7 due Friday, EF Set 8 due Mon. & Quiz on Skills 1-5 on Friday, 9/20.

Formal Set 3 due next Tuesday, 9/24 and Investigating Functions WS due on Block 9/25-26
