You do not need a graphing calculator. In fact a graphing calculator would be a poor way to evaluate this function.
For each X in the chart, simply replace the X in the equation and solve for f(x). For example if X = -2,
f(x) = 2*(-2) - 3 = -6 - 3 = -9
If X = 147, then f(x) = 2*(147) - 3 = 294 - 3 = 291
