their is a graph and a line is labeled y=f(x)
then their are other things similar to the first shape on the graph and i am told to change the y=f(x) to equal these graphs
one is exactly the same but mirrored in the x axis
one is exactly the same but 4 right along the x axis
one is 3 times taller at the y axis and same on x axis e.g. x=1 y=3 but then x=1 y=9
