You can list all the previously computed results by doing the following:

?f

For instance, if you evaluate this:

Table[f[z] = z^2, {z, 10}];

and then evaluate this:

?f

you will get the following output:

f[1] = 1
f[2] = 4
f[3] = 9
f[4] = 16
f[5] = 25
f[6] = 36
f[7] = 49
f[8] = 64
f[9] = 81
f[10] = 100
