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