Hi how would I make a blode plot from this transfer function?
Gp(s) = (10e^-0.25S)/((1+1.2S)(1+3.5S))
is this the correct code in Matlab?

Yes.
The code you posted:
s = tf('s');
g = 10*exp(-0.25*s)/((1+1.2*s)*(1+3.5*s))
figure
bode(g)
grid
should work.
Are you having problems with it?

Thank you really appreciate your help.
Im quite new to Matlab so I just wanted to confirm if I entered this transfer function correctly in the matlab code I sent in the previous message.
Thanks again.

As always, my pleasure!
It looks correct to me. Note that the exponential term is an output delay that primarily affects the phase of the Bode plot.
