how do you do 5.2? the solutions for (f - g)(x) > or equal to O ? 
\(\displaystyle \mbox{5.2. The solution set of the inequality }\, \left(f\, -\, g\right)(x)\, \geq\, 0\, \mbox{ is:}\)
\(\displaystyle \mbox{(A) }\, \bigg(\,-\infty,\, -2\, \bigg)\). . .\(\displaystyle \mbox{(B) }\, \bigg[\, -2,\, \dfrac{3}{4}\, \bigg]\)
\(\displaystyle \mbox{(C) }\, \bigg[\, -2,\, \dfrac{6}{5}\, \bigg]\). . . . .\(\displaystyle \mbox{(D) }\, \bigg(\, -\infty,\, -2\, \bigg]\, \cup\, \bigg[\, \dfrac{3}{4},\, +\infty\, \bigg)\)
