Proposition p: F (x) is the inverse function of F (x) = 1-3x, and / F (a) ^ - 1 / 0}, and a intersection B = empty set For the value range of real number a, there is and only one true proposition in the mission questions P and Q

If a + 2 > 0, b2-4ac > = 0, then a = 0
a> - 2 a > = 0
Because only one of the propositions P and Q is true
