• congruence

• similarity

• function

• mathematical equation

CCSS.8.F.A.1

Determine if the relations is a function and describe the pattern

• Yes it is a function, input goes up 1 and output goes up by 15

• Yes it is a function, input goes up 15 and output goes up by 1

• Not a function, input goes up 1 and output goes up by 15

• Not a function, input goes up by 15 and output goes up by 1

CCSS.8.F.B.4

Determine if the relation is a function

• Not a function, each input has more than one output

• Yes it is a function, because each input has exactly on output

• Not a function, input is equal to output

• Yes it is a function, -1/2 is a fraction of 2

CCSS.8.F.A.1

Determine if the relation is a function

• Yes, each input has one output

• Yes, each output has one input

• No, because the pattern is 4

• No, each input is the same as the output

CCSS.8.F.A.1

Describe the pattern input and output

• The input and output both go down by 3

• The x goes up 1 and the y goes right 1

• The x goes right 2 and the y goes up 2

• There is no pattern
