I need some help with making a program that calculates the value for f(x) = 3x^3 + x^2 +4x -6 and then plot f(x) for x from -1 to 1.

Take a look at the first example on this webpage
and replace the "sin(x)" in it with your polynomial.
Also, to get the range you want, change
x = 0:pi/100:2*pi;
to, for example
x = 0:1/100:1;
