    hint: if we set x=0, into this equation: y= -1/2(5)^x -3 what do we get?

    so like y=-1/2(5)^0 -3 @Michele_Laino

    so it has to be reflected across y-axix 3 units to the right? @Michele_Laino

    your graph is reflected with respect to the x-axis, and since: y= -1/2(5)^x -3= -4 when x=0, then we have: |dw:1440171970254:dw|

    sorry I have made an error: here is the right graph: |dw:1440172177891:dw|

    since: at x=0, we have: \[y = - \frac{1}{2}{5^0} - 3 = - \frac{1}{2} - 3 = - \frac{7}{2}\]

    okay so I'm not sure how to tell if it goes down or right now, I think I was wrong

    as you can see, the shifting was down with respect to the graph of the function: y=(1/2)5^x

    nevertheless that shifting was about \[\frac{1}{2} - \left( { - \frac{7}{2}} \right) = \frac{1}{2} + \frac{7}{2} = \frac{8}{2} = 4\] units, with respect to the graph of: y=(1/2)5^x

    yeah okay I see that it's down x-axis reflected 3 units down. I'm going to have to go back and reread all that you typed. I super super appreciate all that work from you. You rock merci beaucoup!
