Graphing Polynomials Unit 1D Day 19

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

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

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

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