Ran in:
clc
clear
x = 36 ;
y = 10^16 ;
n = -25:-15 ;
f_1 = ( y .^ n ) ./ ( ( exp( x .*n)) ) ;
f_2 = ( y / exp ( x ) ).^n;
plot(n,f_1,"r")
hold on
plot(n,f_2,"b")
legend('f_1','f_2')
xlabel("n")
hold off

hold on is working but except for some NaN's which aren't plotted your functions f_1 and f_2 produce the same values as a function of n so the two curves are on top of each other
