1. The problem asks for the range of an exponential function whose graph approaches the horizontal asymptote $y=3$ on the left and passes through points $(-1, 3.25)$, $(0, 3.5)$, and $(1, 4)$. 2. Recall that the range of an exponential function with a horizontal asymptote $y = c$ is either $y > c$ or $y < c$ depending on whether the function is increasing or decreasing. 3. Since the curve is increasing and approaches $y=3$ from above on the left, the function values are always greater than 3. 4. The points confirm this: at $x=-1$, $y=3.25 > 3$; at $x=0$, $y=3.5 > 3$; at $x=1$, $y=4 > 3$. 5. Therefore, the range is all $y$ such that $$y > 3$$. Final answer: $y > 3$
