How to plot a line where the variable changes condition.

So from 0<x<1.8 Z=1.25*((0.72*(x/5))-((x/5).^2));
and from 1.8<x<5 Z=(1125/1024)*((0.28+(0.72*(x/5)))-((x/5).^2));
Is there anyway I can enter this without putting it into 2 different parts?
Thanks

Z=@(x) 1.25*((0.72*(x/5))-((x/5).^2)).*(x>0 & x<1.8)+...
(1125/1024)*((0.28+(0.72*(x/5)))-((x/5).^2)).*(x>1.8 & x<5);

c = [-.05 .18 0;...
-.0439 .1582 .3076];
b = [0,1.8,5];
f = mkpp(b,c);
xx = 0:.1:5;
plot(xx,ppval(f,xx))
