The graph of a quadratic function `f`is shown on the grid. Which of these best represents the domain of `f`?

-4≤x ≤ 5
y≥-12.25
All real numbers
All real numbers less than -4 or greater than 5

The best representation of the domain of `f` based on the given graph would be -4 ≤ x ≤ 5. This is because the graph only exists between x-values of -4 and 5. The other options do not accurately represent the domain of the graph shown.
