Bellwork Day One

• A bag of apples that weighs 8 pounds costs $2.89. Which is closest to the cost of 3 pounds of apples at the same rate?

• F. $0.36

• G. $0.96

• H. $1.08

Word of the Week

• Direct Variation (direct proportion): When values vary so that one increases or decreases a specific amount, the other value increases or decreases by a constant.

• Example: If Melissa earns $8.25 per hour, then the amount she earns is in direct variation with the number of hours she works.

1.Give the proper name for this chart

2.F. y = 2x + 3G. y = 3x + 2H. y = 3xJ. y = 2x

Objective

• I can create functions and find missing values in function tables

• I can graph the relationship on a coordinate plane.

Function & Function Tables• Function: A function is a special relationship

between values: Each of its input values gives back exactly one output value. Example: y=2x+1 b=5a

• Function Table:A function table displays the relationship between the inputs and outputs of a specified function (x value is usually above or left)
