ACT Practice

Objectives Students would be able to: u Compare functions that are closed under addition, subtraction, and multiplication to functions that are not closed under these operations. u Analyze the meaning for polynomials to be closed under an operation. u Compare integer and polynomial operations. Mastery is evidenced by scoring a 3 out of 4 on the Exit Slip

Common Core Standards A-APR Arithmetic with Polynomials and Rational Expressions Perform arithmetic operations on polynomials 1. Understand that polynomials form a system analogous to the integers, namely, they are closed under the operations of addition, subtraction, and multiplication; add, subtract, and multiply polynomials.

Terms to Know

Graphs of polynomials are: 1. Smooth 2. Continuous 3. Increase or decrease to infinity as x approaches positive of negative infinity

Describe the similarities between polynomial and integer operations.
