# Math Help - Range of a function?

1. ## Range of a function?

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.

No the range would be $(4, \infty)$

3. by adding 4 you shift the graph up 4 units

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