Unit 1D Day 19

2. Do Now Fill in the chart about end behavior. Use your notes!
leading coefficient
positive/ negative
degree
even/ odd

3. Review End Behavior
Describe the end behavior of each of the following.
f(x) = x2 – 2x – 15
As x  +∞, f(x)  ____
As x  -∞, f(x)  ____
f(x) = 12x3 + 2x2 – 30x – 5

4. x-intercepts Find the x-intercepts of each of the following.
f(x) = x2 – 2x – 15
f(x) = 12x3 + 2x2 – 30x – 5

5. Sketching Polynomials
Sketch each of the following using the end behavior and x-intercepts.
f(x) = x2 – 2x – 15
f(x) = 12x3 + 2x2 – 30x – 5

6. Sketching Polynomials
Sketch each of the following using end behavior and x- intercepts.
f(x) = -9x2 + 55
f(x) = -x2 + 7x – 12
