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?

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.
