I suggest you spend a few weeks reading the introductory sections of The Mathematica Book or some other text on Mathematica. You'll find it is a worthwhile investment. In[1]:= f[x_] := 2*x^3 - 3*x^2 - 12*x In[2]:= Plot[f[x], {x, -2, 2}, Epilog -> {{Hue[1], PointSize[0.020], Point[{0.5, -6.5}]}, Line[{{0.5, 0}, {0.5, -6.5}, {0, -6.5}}]}] Try to use non-capitalized letters when you define a function.
