Absolute Value
F(x)= |x|
Tests for Symmetry
1. y-axis if f(x)=f(-x)
2. x-axis if y = -y
3. origin if -x and -y = x and y
Slope of a line
m= y2-y1 / x2- x1
Point slope equation of a line
y-y1 = m(x-x1)
Slope intercept
y= mx + b
Parallel and Perpendicular lines
m1 = m2
m1 = 1/-m2
Transformations
y=f(x) original
y= f(x-c) shifts right
y = f(x+c) left
y=f(x)- c shifts downward
y= f(x) + c shifts upward
Reflection
y= -f(x) x-axis
y= f (-x) y-axis
y= -f(-x)
Even and Odd
F(-x) = f(x) even
F(-x) = -F(x)
