I need help with this problem.

Graph f(x). then reflect the graph of f(x) across the y-axis. Write a function g(x) to describe the new graph.

f(x)=2x+4

Can anyone help me? I would be so happy! :D

To learn how to graph linear functions, try here. To learn how to do function transformations, try here. To learn how to find straight-line equations from points (in this case, from a couple points in your transformation graph), try here.

The lessons in the links should be enough to get you started. Once you've studied them, please attempt the exercise. If you get stuck, please reply with specifics regarding where you are getting stuck. Thank you! :wink:
