MS Algebra A-F-IF-1 – Ch. 5.1 Functions as Ordered Pairs ALGEBRA SUPPORT Represent Functions as Ordered Pairs with a Domain and a Range

SUPPORT Class Learning Target Title: 5.1 Functions as Ordered Pairs Date: SUPPORT Class Learning Target By the end of the period, I will represent a function as a set of ordered pairs with a domain { x } and a range { f(x) }. I will demonstrate this by completing Four-Square Notes and by solving problems in a pair/group activity.
