Hi Jurimagic,

It is an exponential graph.

5.5 to the power of anything must be bigger than 0

and so (5.5 ^x)+1 must be bigger than 1

 

 

As x get big in the positive direction  y gets VERY big.

When x=0 y=2    (edited)

As x tends to negative infinity, y gets closer to 1 (but it will always be bigger than 1)

so

y=1 is an asymptote.

 

Here is your graph

Actually Melody, when x=0 y=2 

As (5.5^0)=1 

1+1=2

Hi Melody,

 

gosh I always tend to overthink things...it's really very simple....I should apologise for waisting your time on something like this...sad...sorry..
