Ok hi

I have a unit test tomorrow regarding transformations and conics. I'm working on some problems on transformations regarding the stretches.

Now, the orig formula (or equation) is y=f(x)

then i have to sketch y=1/2f(1/2x)

what can be done to solve this?

i got y -> 2y and x -> 1/2x this means that i can multiply 2 by y coords on orig points and 1/2 by x coords on orig points to find new points of a transformed drawing? Right?

Thanks
