Expert Solution
NOTE:

As per our guidelines, we can answer only three sub-parts in a single request. Kindly re-post the other sub-part(s) in a separate request.

Sub-part (a)

Given that, Ux=-20x2+560x-1500Here, the leading coefficient of Ux=-20<0As leading coefficient is negative, therefore the parabola is concave down.
