Evaluate the "inner" function and use that function value as input to the "outer" function. For example,

t(p(-1))....
The table shows p(-1) = 1; now evaluate t with that input value
t(1) = -2

t(p(-1)) = t(1) = -2

The others are all similar; you can do them.

Note that some of the composite functions shown might not be defined. For example, t(p(-2)) is not defined, because p(-2) = 4 but t(4) is not defined.
