QuestionFind the range of the function $f(x)=-e^{2-x}-3$. A $(-\infty, \infty)$ B $(-\infty,-3)$ C $(3, \infty)$ D $\quad(-3, \infty)$

Studdy Solution
Therefore, the range of $f(x)$ is $(-\infty, -3)$, since it can take any value less than $-3$ but not $-3$ itself.
The correct answer is: B $(-\infty, -3)$
