f(x)= x squared
LINEAR FUNCTION
f(x)=mx+b
g(x)=f(x+m)
SHIFT LEFT by m
g(x)=f(x-m)
SHIFT RIGHT by m
g(x)=f(x)+m
SHIFT UP by m
g(x)=f(x)-n
SHIFT DOWN by m
g(x)=m*f(x)
STRETCH VERTICALLY by m
g(x)=f(m*x)
COMPRESS HORIZONTALLY by 1/m
g(x)=f(m*x), m<1
STRETCH HORIZONTALLY
g(x)=f(x)*m, m<1
COMPRESS VERTICALLY
g(x)= -(f(x))
REFLECTION ACROSS X AXIS
up becomes down and vice versa
g(x)=f(-x)
REFLECTION ACROSS Y AXIS
left becomes right and vice versa
f(x)=mx+b
LINEAR FUNCTION
Linear Function
f(x)=mx+b
