A) $( - 2,0 ) , \left( \frac { 1 } { 3 } , 0 \right)$
B) $\left( - \frac { 1 } { 3 } , 0 \right) , ( 2,0 )$
C) $\left( - \frac { 2 } { 3 } , 0 \right) , ( - 1,0 )$
D) $\left( \frac { 2 } { 3 } , 0 \right) , ( 1,0 )$

The x-intercepts are found by setting $f(x) = 0$. Solving $3x^2 + 5x - 2 = 0$ using the quadratic formula gives the roots $x = -2$ and $x = \frac{1}{3}$.
