Question 1118317: Take the basic graph of f(x) = 2^x. Now we are going to perform a transformation: f(x) = 2^(-x +3). The graph of this function is the graph of the original function reflected across the y axis. We also have a horizontal shift, and it is here that I have a question. My understanding is that a +3 would cause a shift to the left of 3. However, when I plot this function using a graphing utility it is shifted to the right. Why do I see this discrepancy?
Thanks.

Question 1118616: Last question of the day. I need to check my work on the following equation:
0.03(3-7x)-0.02(1-x)=0.64
I solved the equation which is -3, but I cannot for the life of me figure out how to check this answer. I have checked my textbook, and see no examples. I know I should place -3 in place of x, but it doesn't seem to work.
I have tried 0.03(3-7(-3))-0.02(1-(-3))=0.64 and 0.03(3-7-3)-0.02(1-3)=0.64
each do not produce a TRUE answer.
Thank you for your help.
