Can someone help me with these question. i can;t find any notes for it.

11 (a) (i) Sketch the graph of y=a(^x) + 1, a>2

(ii) on the same diagram, sketch the graph of y = a(^x+1) , a > 2

**0**

These are just graph transformations.

For part (i), I think the easiest way to see this is to think of the "normal" exponential graph . Then the extra "+1", will just increase each

For (ii), if you say , then , and this has the effect of shifting the graph one place to the left.

*y*-coordinate by one (i.e. shift the graph up one unit).For (ii), if you say , then , and this has the effect of shifting the graph one place to the left.
