Please help me in writing the program for determining zero of the function f(x)=k-3kx^2+3x^3 when k=1,1.5,2,2.5,3,3.5, ........,6

Question

i need a program to determining zero of the function which is cubic in nature

 

f(x)= K- 3Kx²+3x³        

when  k takes values from 1-6

Answer 1

If you have MATLAB, then try writing this code exactly as it is written:

 

k = [1:0.5:6];

f(x) = [3, -3*k, 0, k];

x = roots(f(x))

 

Then once you written the last line of the code, press ENTER.  It will give you all the possible solutions at these k values.  If you have any questions about this MATLAB code, let me know.
