function V_out = Final_part4(V_in, R1, R2)
V_out = (R2/(R1+R2))*V_in;
if R1 <=0 && R2<= 0
error ('No negative numbers allowed');
end
end
My question is how do i have the output show error when R1 and R2 are less than zero,

The code you have will throw an error and abort the function if the conditions are met. It should not return anything in V_out.
Actually, although neither R1 nor R2 can be negative, R2 can be zero providing R1 is greater than zero. In that case, the little voltage divider network shorts the output to ground, and V_out = 0.

I believe you want
if R1 <= 0 || R2 <= 0 % or <
instead of
if R1 <= 0 && R2 <= 0
This will throw an error if either is less than 0
