>Describe how the grah of each of the following functions can be obtained from the graph y=f(x)

3f(2x)-6

2. Relevant equations

f(x)=a(x-h)k

y=f(x)

3. The attempt at a solution

I know that its going to be a vertical stretch by a factor of 3, and a horizontal compression by a factor of 1/2 . But i have two questions, when its horizontal comrpession do i always turn it into a fraction? , and when its something like y=f(1/2x) -6 , what do i multiply the 1/2 by to get the actual value for the horizontal stretch?

Also, How do i graph it? Do I have to use a table of values, Always? inorder to get the points for the horizontal compression/stretch or is there an easier way?

Like with vertical stretch / compression you can multiply the step pattern 1,3,5 by whatever the a value is.
