Explanation:


C(x)=4x^2-3\\\\C(0),\ C(-1),\ C(-2),\ C\left(-(3)/(2)\right)\\\\\text{Substitute each value}\ \left\{0, -1, -2, -(3)/(2)\right\}\ \text{instead}\ C(x):\\\\C(0)=4(0^2)-3=4(0)-3=0-3=-3\\\\C(-1)=4(-1)^2-3=4(1)-3=4-3=1\\\\C(-2)=4(-2)^2-3=4(4)-3=16-3=13\\\\C\left(-(3)/(2)\right)=4\left(-(3)/(2)\right)^2-3=4\left((9)/(4)\right)-3=9-3=6
