1. The problem asks to write the domain of the given function using interval notation. 2. The graph shows a parabola opening upwards between $x = -1$ and $x = 4$ with open circles at $(-1, 2)$ and $(4, 2)$. 3. Open circles mean the function does not include those endpoints. 4. Therefore, the domain includes all $x$ values strictly between $-1$ and $4$. 5. Using interval notation, the domain is $$(-1, 4)$$. 6. This means the function is defined for all $x$ such that $-1 < x < 4$. Final answer: The domain is $$(-1, 4)$$.
