yep. got A.you test a point within the region, e.g. (3,0) the only conditions wich adhere to this point are in A. so A is correct, C is not
+1, tested the same point aswell hahaLolol it's really not that hard.
For the parabola equation, the shaded region is within it.. so you test (0,0) into the equation and find an inequality that satisfies it.
For the line, the shaded region has (3,0) in it, so you sub (3,0) into the equation and find one which satisfies it.
If the inequalities that satisfies the answer is correct.
