How to plot two different symbolic functions on the same figure?

I need to know how to plot two different symbolic functions on the same figure. The variable is x. In the 1st function x ranges from 0 to 0.9 and in the 2nd function x ranges from 0.9 to 1.8

I tried using the "hold" command in between two "ezplot" commands. but that didn't work. Maybe because the x range is different.

Try using fplot where I randomly chose f1 and f2:

syms x;

f1=symfun(x,x);

f2=symfun(x^2,x);

fplot(f1,[0,0.9]);

hold on;

fplot(f2,[0.9,1.8]);
