Why do i need to use the .^ notation ? Is there any other way around it ?
% This is my function.
function y = PBTask4P1_f(x)
y = 4.2*x.^4-5*x.^3-7*x;
plot(x,y);
xlabel('INPUT X')
ylabel('OUTPUT Y')
end

It's based on equation. .^ represent the element wise to the power of any array/vector.
See the example
a =
1 2 3 4 5 6
>> a.^2
ans =
1 4 9 16 25 36
Whereas a^2=a*a (Matrix Multiplication)
