Answer

Graph A

Work Step by Step

We are given the function $f(x)=3x^{2}-2$. The degree of this polynomial is 2, so the function will have the shape of a parabola (like the functions shown in graphs A and C). However, the coefficient on x is positive $(3\gt0)$, so the parabola will open upward. Therefore, this function matches graph A.
