Use these variables to plot the graphical representation of the polynomial.

To that end, you must use the function plot, using two parameters, 1)

the vector created in step b and 2) the polyval function (also with two

parameters, the vectors created in steps a and b, in that order).

v1 = [1 -2 -5 6] % vector from exercise A

v2 = [-100 : .1 : 100 ] % vector from excercise B

@Jonas Morgner, Do you mean llke this?

v1 = [1 -2 -5 6];
v2 = -100 : .1 : 100;
y = polyval(v1, v2);
plot(v2, y)

Yes that works! Thank you very much :)
