Evaluate the function f(x)=2x-2 when x equals negative 1<br> A. -4<br> B. -3<br> C. 0<br> D. 4

Just plug in -1 for your x in 2x-2 and solve like a normal equation. Think of f(x) a your y because that's basically what it is. If it helps, the equation is basically:
y=2x-2 so you would just solve for y by plugging in -1 into x.
