CCSS.HSF.IF.A.1

Given this set of ordered pairs, state the range.

• (1, 2, 3, 4, 5)

• ( 1 )

• (1, 4, 9, 16, 25)

• The range does not exist

CCSS.HSF.IF.A.1

This is called a ______________

• quadrant

• coordinate plan

• a graph

• a function

CCSS.5.G.A.1

Is this a function?

• Yes because each domain value has only one range value

• Yes, because each range value has only one domain value

• No because the elements of the domain are paired with more than one element of the range

What is the vertical line test?

• A vertical line is drawn to determine if the graph represents a function

• a vertical line is drawn to determine if the graph represents a relation

• A vertical line is drawn to separate relations and functions

• A test to see if the domain is equal to the range

If my function rule is y=x + 3, what is the OUTPUT if the input is 4?

• 4

• 3

• 7

• 10

CCSS.HSF.IF.A.1

Is the relation a function? Why.

• Yes, because the x-value 11 has two y-values pair with it.

• Yes, because each x-value has only one y-value paired with it.

• No, because the x-value 11 has two y-values pair with it.

• No, because each x-value has only one y-value paired with it.
