Everywhere you see an x, replace it with 330. Then evaluate. Use the unit circle to find the values of sin(330) and cos(330)
[tex]g(x) = 4\cos(x)-2\sin(x)\\\\g(330^{\circ}) = 4\cos(330^{\circ})-2\sin(330^{\circ})\\\\g(330^{\circ}) = 4\frac{\sqrt{3}}{2}-2\left(-\frac{1}{2}\right)\\\\g(330^{\circ}) = 2\sqrt{3}+1\\\\[/tex]
