Math 12 Transformations
Example 1: Combining Stretches and Reflections
Identify each parameter in the general transformation equation: y = af[b(x
- h)] + k.
a is the vertical stretch factor.
b is the reciprocal of the horizontal stretch factor.
Example 1 Solve
Theres really not a whole lot to do in solving this kind of trig equation. All we need to
do is divide both sides by 2 and the go to the unit circle.
So, we are looking for all the values of t for which
