In Problems 1-6, graph the region R bounded by the graphs of the equations. Use set notation and double inequalities to describe R as a regular x region and a regular y region in Problems 1 and 2, and as a regular x region or a regular y region, whichever is simpler, in Problems 3-6.
(A) y = x2, y = 9, 0 ≤ x ≤ 3
(B) y=5-x,y=1+ x, y = 0
(C) y = 4 + 3x - x2,x+y = 4
