How to plot a piecewise function on Matlab?

I need to plot the two piecewisely defined functions on the same graph. Please help me to write code. Thanks in advance.

f(x)= 1-sqrt{5-x} for x =<5,

1 for 5=< x =<7,

1-sqrt{(x-7)/3} for x =>7.

Similarly,

g(x)= sqrt{(5-x)/2} for x =<5,

0 for 5=< x =<7,

sqrt{(x-7)/5} for x =>7.

You can try the another function.

syms f(x)
f(x) = piecewise(x<=5, 1-sqrt(5-x), 5<x<7, 1, x>=7, 1-sqrt((x-7)/3) )

f(x) = 

fplot(f, [0 10])

Thanks Dear Chunru! Please help me to plot both functions in a single plot.

Try define another function. Then "hold on"; and plot the function.

Ok, Thanks a lot!
