Question:

A polynomial function p is defined by \(\mathrm{p(x) = (x - 8)(x - 2)(x + 3)}\). A second function, q, is defined by the equation \(\mathrm{q(x) = p(-x)}\). The graph of \(\mathrm{y = q(x)}\) in the xy-plane has x-intercepts at \(\mathrm{(r, 0)}\), \(\mathrm{(s, 0)}\), and \(\mathrm{(t, 0)}\), where r, s, and t are distinct constants. What is the value of \(\mathrm{r + s + t}\)?
