Reflection over Y-axis

Negative on inside y = (==-==x+3)

Reflection over X-axis

Negative on outside y = ==-==(x+3)

Translation up/down

Add on outside y = x==+1== or x==-1==

Translation left/right

Add on inside y = 3(x==-1==)+5 or 3(x==+1==)+5

Vertical stretch/shrink

Multiply everything y = ==3==(x+1) or ==1/3==(x+1)

Horizontal stretch/shrink

Multiply inside y = ==3==x+1 or y = ==1/3==x+1

When doing horizontal stretches…

Take reciprocal
