- h(x)=f(x)+k
- vertical shift k units up
- h(x)=f(x)-k
- vertical shift k units down
- h(x)=f(x+k)
- horizontal shift k units left
- h(x)=f(x-k)
- horizontal shift k units right
- h(x)=-f(x)
- reflection over the x axis
- h(x)=f(-x)
- reflection over the y axis
- h(x)=/f(x)/
- negative parts of the graph become positive (negative parts are reflected over the x axis)
- h(x)=f(/x/)
- right hand part of the graph stays the same. Left hand part is a reflection of the right hand part
- even function
-
f(-x)=f(x)
y-axis symmetry - odd funtion
-
f(-x)=-f(x)
origin symmetry
