>> x = -5:1:5;
>> y = exp(x)*(x.^3-5*x.^2+5*x+1);
Error using *
Incorrect dimensions for matrix multiplication. Check that the number of columns in the first matrix
matches the number of rows in the second matrix. To perform elementwise multiplication, use '.*'.

Unrecognized function or variable 'y'.

You missed a spot where you needed an element-wise operation, multiplying the exp(x) by the other term:
x = -5:1:5;
y = exp(x).*(x.^3-5*x.^2+5*x+1);
