Exponential Functions

[haleym]

I need to write 2 equations that represent the same exponential function with a y-intercept of 5 and an asymptote at y=3. I got y=2^(x+1) + 3 but I don't know how to find the second equation. Can someone please explain this to me. Thanks.

Since the y- intercept is at (0, 5) and the asymptote, y= 3, is symmetric about the x-axis, try "reflecting" that graph in the y-axis. That is, replace your "x" with "-x".

Thank you!
