## Homework Statement

I don't particularly need help with any one problem, I just need a refresher on how to find the Key Point and Asymptote of an equation like the following:

*f(x)=2^(x+2)+3*

Y-Int=?

Key Point=?

Asymptote=?

## Homework Equations

I'm pretty sure I'll only need the original equation

*f(x)=2^(x+3)+3*and the unmodified equation

*f(x)=2^(x)*lthough I'm not sure if my unmodified version is right.

## The Attempt at a Solution

From what I remember, to find the Y-Intercept I need to set X equal to zero, and so:

*f(x)=2^(0+2)+3*

f(x)=4+3

f(x)=7

f(x)=4+3

f(x)=7

And so the Y-Intercept would be (0,7)

I alos remember that finding Key Point has something to do with finding the Y-Intercept without any of the additional modifiers in the equation:

*f(x)=2^(0)*

f(x)=1

f(x)=1

I'm not even sure I did that right, but assuming I did, I do not know what to do with the answer. I remember I somehow combine it with the Y-Intercept, but I simply cannot remember how.

For the Asymptote, I believe I simply take the number that modifies the X and set it equal to X:

x=2

Again, I'm not sure about this, so any help would be greatly appreciated
