- Lesson Plan →Objectives, pacing and practice, built from this lesson's brief.
- Guided Notes →One page your students fill in and keep.
- Exit Ticket →Three items at the end of class. No student accounts.
- Re-teach →After an exit ticket: who missed what, and what to do tomorrow.
- Homework →Assign practice; it grades itself.
**A 505.** Add, subtract, and multiply polynomials
**A 513.** Determine when an expression is undefined
**AF 602.** Build functions and write expressions, equations, and inequalities for common algebra settings (e.g., distance to a point on a curve and profit for variable cost and demand)
**AF 702.** Build functions and write expressions, equations, and inequalities when the process requires planning and/or strategic manipulation
**AF 703.** Analyze and draw conclusions based on properties of algebra and/or functions
**A 403.** Solve routine first-degree equations

What you'll learn
- State the pointwise definition $(f+g)(x) = f(x) + g(x)$, and the corresponding definitions for difference, product, and quotient
- Evaluate $(f+g)(a)$, $(f-g)(a)$, $(fg)(a)$, and $(f/g)(a)$ from the two functions' values at $a$
- Write the simplified expression for a sum, difference, or product of two polynomial functions, distributing a subtraction correctly
- Identify the values excluded from a quotient function because the divisor function is zero there, and explain why neither original function shows the restriction
- Build a combined function in an applied setting — profit as revenue minus cost — and interpret its parameters and its zero
