f(x)=sin(x)-x^5=0 providing x is not equals 0

>> [x0,fval]=fzero(@(x)sin(x)-x.^5,[0.8,1])
x0 =
    0.9610
fval =
  -1.1102e-16

x = -10:0.05:10;

fun_x_1 = exp(-0.3*x(x<0));

fun_x_2 = sin(x(x>=0).^3)-sin(x(x>=0).^2)+1;

plot(x(x<0),fun_x_1,x(x>=0),fun_x_2)

x = input('x value: '); 
y = input('y value: ');
k = x * y;
if k == 6 % <-- Use == for equality test
    k1 = 2; 
elseif k == 0 
    k1 = 1; 
end

Note that there is a path for k1 to be unset if k is not 6 or 0. You might need to cover this case in your code.
