I'm looking for a bit of help on something that should be pretty easy, but I'm not quite understanding how to go about this.
The assignment question is as follows:
For the function y = f(x) graphed below. Sketch each function on the grid provided.
For each graph: a) explain what changes you made to y = f(x)
b) Give the new coordinates of the point provided in each question.
The question then is to transform the graph to y = f(1/2x), the point given to me to give the new coordinates for is (4, 2).
Maybe I'm missing something here but wouldn't I have to have the actual function of the graph given to me before I can transform it? Or should I be able to do it with just a sketch of the original function?
Thanks for any help, I'm doing an online class thats the equivalent of high school level stuff but it's been a few years since I've done any math courses so I am even having trouble with the basics!
