the graph of y=f(x) is shown. draw the graph of y= f(2x) -1

Question

i need help. the original coordinates are (0,0) (-2,4) (4,2)

Answer 1

Hi Draco,

Based on what you are expressing, the original coordinates are solutions to f(x). Why don't you make a function table for y = f(x) and Y=f(2x)-1, observe the solutions to Y=f(2x) -1 and compare the 2 functions?Doing this will certainly help you. You should also look in your class notes/lecture video to see how you can describe this morphing of the function y to Y.

Please give it a try and enter a sentence or two for your observation in the comment box. I will take a look into it in about 30 minutes from now to see the progress you have made..
