exponential functions problem, help please?

Question

please help, i think this is even harder than algebraic functions and inverses. i really suck at math. *sighs*

have to get the following for each problem

a) domain and range
b) y-int
c) equation of asymptote
d) look of the graph

problem # 1

f(x)=(2 raised to x-1) + 3


problem # 2

g(x)=(4 raised to 3-x) - 1

THANKS A WHOLE LOT!!!

f(x)=(2 raised to x-1) + 3
Domain R
Range (3, infinitive)
asymptote y = 3
increasing function

g(x)=(4 raised to 3-x) - 1
Domain R
Range (-1, infinitive)
asymptote y = -1
decreasing function

I don't think anyone should give you the answers.

Give it a try first and show us in the details section...then, if you have a specific question, maybe we can help.

I don't want to encourage or participate in dishonesty and I don't want to hurt your future SAT scores, because you need to learn this stuff.

I'm not mad, I'm just trying to be a responsible adult.

(2/3)^x=9/4 (2/3)^x=(2/3)^2 x=2

you DO know that A^(g(x)) = e^(g(x) ln A)???....with this you can answer the first 3 parts and possibly the 4th also
