Common Core For Algebra I
• Students use function notation, evaluate functions for inputs in their domains, and interpret statements that use function notation in terms of a context.
• Students create functions that represent a geometric situation and relate the domain of a function to its graph and to the relationship it describes.
Lesson 8 Summary
• Formulas that represent a sequence of numbers have a set of inputs; each input number is used to represent the term number. The outputs of the formula listed in order form the sequence.
• Formulas that represent different situations such as the area of a square of side x can have a set of inputs consisting of different subsets of the real number system. The set of inputs that makes sense depends on the situation, as does the set of outputs.
Lesson 8 Exit Ticket
Recall that an odd number is a number that is one more than or one less than twice an integer. Consider the sequence formed by the odd numbers {1, 3, 5, 7, ...}.
1. Find a formula for O(n), the nth odd number starting with n = 1.
2. Write a convincing argument that 121 is an odd number.
3. What is the meaning of O(17)?
