#1) Match each graph below to an equation that it represents. Use the EQUATION BANK to determine which equation goes with each graph.

• c

• y = 3|x + 3|

• d

• y = 3|x| + 3

• b

• y = 3|x| - 3

• a

• y = 3|x - 3|

#2) What are the x-intercepts of the graph of y = (3x - 2)(4x + 3)(x - 4)?

• (-2/3, 0), (3/4, 0), (-4,0)

• (2/5, 0), (-3/4, 0), (4,0)

• (-5/3, 0), (1/4, 0), (3,0)

• (3/5, 0), (4,0), (3,0)

• 98

• -98

• -16

• 16

• 98

• -98

#5) Match each end behavior below with the polynomial it represents. Use the POLYNOMIAL BANK to determine which polynomial goes with each end behavior.

• As x approaches positive or negative infinity, f(x) approaches positive infinity.

• As x approaches positive or negative infinity, f(x) approaches negative infinity.

• As x approaches positive infinity, f(x) approaches negative infinity. As x approaches negative infinity, f(x) approaches positive infinity.

• As x approaches positive infinity, f(x) approaches positive infinity. As x approaches negative infinity, f(x) approaches negative infinity.
