What?
A K P Q is the transformations from the original function
A
A is the amplitude
if a > 1 then vertical stretch if a < 1 then vertical compression
K
if k > 1 then horizontal compression if 0 < k < 1 then horizontal stretch
P
if p > 0 then translate left if p < 0 then translate right
Q
Vertical translation up or down if q > 0 then translation up if q < 0 then translation down
