Hi everyone. This is my first post here, and I hope I am doing
everything right. Please feel free to correct me if I've done
anything wrong. Thanks in advance for taking the time to read
through my frustrating issues. Okay, so I'm doing
transformations using y=af[K(x-d)]+c. I know that K>1 =
horizontal compression of a function and 0<k, & K<1 = horizontal
stretch of a function. I've been given the base function f(x)=x,
and have been told that it is being stretched horizontally by a
factor of 1/2, and having some other transformations applied to
it. I understand everything else that's been provided in the
answer, but I don't understand what's going on with K. The
answer the text provides states that, since the graph is being
stretched horizontally by a factor of 1/2, then K=2. How does
K=2? Shouldn't it equal 1/2? Also, if K=2, then the graph is
being compressed horizontally rather than stretched, correct?
What is going on here? Is my text book wrong? Or am I not
getting something? it's occurring to me that I
