Question

How do you graph `y=3(1.9)^x`?

Answer 1

See below.

Explanation:

`y= 3(1.9)^x`

`y` has the standard exponential graph of `y=a^x` where `a=1.9` scaled by a factor 3. `y` has the attributes below:

`y(0) = 3`

Domain of `y = (-oo,+oo)`

`lim_(x->+oo) y -> oo`

`lim_(x->-oo) y =0`

Thus, Range of `y = (0,+oo)`

The graph of `y` is shown below.
