a) Find the zeros and y-intercept
b) Describe where the function is positive or negative
c) Describe where the function is increasing or decreasing
d) Describe the end behavior.
e) Sketch a graph of the function
1)
f ( x ) = ( x + 1 ) ( x − 2 ) ( 3 x − 1 )
A.) f (x) = (x+1) x (x-2) x (3x-1)
f(0) = (0 + 1) x ( 0-2) x(3x0-1)
f(0) = 1(0-2) x 3x0-1)
f(0)= 1x (-2) x (3x0-1)

2)
f ( x ) = 2 x ( x 2 − 16 )

3)
f ( x ) = ( 2 x 2 − 9 x − 5 ) ( 9 x 2 − 16 )

4)
f ( x ) = ( x 2 + 3 x + 2 ) ( 8 x 2 − 10 x − 7 )

What are the domain and range of the functiony = 2(x - 3)2 + 4?

Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, –6) is rotated 90° counterclockwise. (x, y) → (–y, x) 1. switch the x- and y-coordinates: (6, –3) 2. multiply the new x-coordinate by –1: (6(–1), –3) 3. simplify: (–6, –3) .

According to the 2008 u. s. census, california had a population of approximately 4 × 10^7 people and florida had a population of approximately 2 × 10^7 people. which of the following is true? a. the population of florida was approximately two times the population of california. b. the population of florida was approximately twenty times the population of california. c. the population of california was approximately twenty times the population of florida. d. the population of california was approximately two times the population of florida.
