Chapter Two
•
Equations –statement where two expressions are equal
•
Slope – change in the dependent variable divided by the change in the independent variable
o
If X changes by one units, Y changes by m units
o
M is a parameter and multiplier
•
Intercepts
o
XIntercept: plug in 0 for Y
o
YIntercept: plug in 0 for X
Chapter Three
•
Function – mathematical rule that assigns for each value of Y, only one variable of X
o
Value of Y depends on the value of X
o
Rational function: f(x)= g(x) / h(x)
o
Composite functions:
o
Explicit function: all variables, except y, are on right hand side
•
Quadratics
o
Quadratic formula
o
Vertex:

b2a f b2a
Chapter Four
•
System of Equations
o
N equations with v variables = dimensions of n x v
If n=v then a exactly constrained system
If n < v under constrained system; unlimited or no solutions
If n> v then an over constrained system
o
If equations are parallel the equations are inconsistent
