@Moo I think I found the problem. f[x] was evaluating to 0, even after I assigned it an expression. Entering Clear[f] seemed to correct it. I'm not sure what I had done to cause me to be unable to change the expression stored in f. Does the := do something different than =?. Thanks.

@Moo Could you post exactly what you entered? I'm running MMA 10 on Win7. I'm not sure what you mean by "Enter f[x] on its own line first". Even if I evaluate the line with the function definition before using it in Solve I get the same result.
