Below is the graph of a trigonometric function. It intersects its midline at $(1.25,-2.75)$ and it has a minimum point at $(4.75,-6.25)$. What is the period of the function? Give an exact value.
$+\stackrel{x}{=}$ units

Please directly answer the question and provide the final value, e.g., 1, 2.5, 300.
