Formulas and Key Relations

1. Basic Terms and One-Variable Polynomials

4x + 5y + 3

200l + 160w + 50lw

x(10 - x) or 10x - x²

2. Degree and Classification of Polynomials

Highest power of the variable = degree

3. Linear Polynomials and Linear Equations

2x + 10 = 64

x + (x + 10) = 64 → 2x + 10 = 64 → 2x = 54 → x = 27

4. Input-Output View of Polynomials

2x + 3

Linear growth and linear decay

In Example 9, the journey cost function is C(d) = 100 + 60d.

2x + 3 gives output 11 when x = 4.

2x + 3 gives output -9 when x = -6.
