1 . look at it

2 . a . see that 3 \times 1 - 2 = 1

2 . b . see that \sqrt{1} + \sqrt{3 \times 1 - 2} = 1^{2} + 1

\begin{array}{ccccc} f (x) & g (x) & \cap x = \\ \sqrt{x} & x^{2} & 1 \\ \sqrt{3 x - 2} & x^{2} & 1 \\ \sqrt{x} + \sqrt{3 x - 2} & 2 x^{2} & = 2 \\ \sqrt{x} + \sqrt{3 x - 2} & x^{2} + 1 & = 2 \end{array}

s o l u c i o n x = 1
