1. Degree
The degree of a polynomial is the value of the highest exponent.
E.g. 5x3 - 4x2 + 7x - 8
The highest exponent is 3,  the degree of this polynomial is 3
y = -6x + 39
The highest exponent is 1,  the degree is 1
This is a linear function (in the form y = mx + b)
Linear functions have a degree of 1
y = 3x2 + 2x + 16
The highest exponent is 2,  the degree is 2
This is a quadratic function (in the form y = ax2 + bx + c)
Quadratic functions have a degree of 2

2. Function Notation f(x) is called function notation
It is read as “f of x” or “f at x”
E.g. y = 2x - 7 would be written as f(x) = 2x - 7 in function notation
f(2) = 5
This means that when x = 2, y = 5

3. FOIL
Firsts
Outsides
Insides
Lasts
E.g. Expand (x + 3)(x - 5)
