State the range of the function: f(x) = 3^(x+9) + 4 I believe that the answer is: (-1, infinity) Am I correct? Any help is appreciated.

by adding 4 you shift the graph up 4 units

hi i think for every real $\displaystyle x$ your function is strictly positive, $\displaystyle \forall x\in \mathbb{R},f(x)> 0$. therefore the range is $\displaystyle (0,+\inf)$.
