How to write piecewise function in symbolic form?

I have to make a piecewise function in symbolic form using the following:

-2 <= t <=-1, t+2,

-1 < t <=1, 1,

1<t <=2, -t+2

otherwise 0

i tried the code below but it seems to be giving me errors. Any idea what I'm doing wrong?

syms x(t)
x(t) = piecewise(-2 <=t && t <=-1, t+2,-1 < t && t <=1,1,1<t && t<=2,-t+2 ,0);
fplot (x(t))

Use &, not &&

syms x(t)
x(t) = piecewise(-2 < t & t <= -1 , t+2,  -1 < t & t <= 1, 1, 1 < t & t <= 2, -t+2, 0)

x(t) = 

fplot(x(t),'-o')
