As an example of what I input and receive:
In[1]:= f[x_] := x^2 + 2
In[2]:=f[x]
Out[2]:=Hold[f[x]]
How can I get mathematica to display the function instead of " Hold[f[x]] "?
Edit 1: A test yields:
In[279]:= f[x_]:=2*x^2
In[280]:= f[x]
Out[280]= Hold[f[x]]
In[282]:= ReleaseHold[Hold[f[x]]]
Out[282]= Hold[f[x]]
In[281]:= 2*3
Out[281]= 6
In[283]:= ReleaseHold[f[x]]
Out[283]= Hold[ReleaseHold[f[x]]]
Edit 2: After a lot of frustration I took the nuclear option. A complete reinstall fixed the issue.
