Is there a Continuous Function f:R-->R Discontinuous at All Other Numbers?
So f(x)=(x-π)^18 for x rational and 0 otherwise should work I think! Thank you very much

Are there any other twin primes with this property?
The twin primes 5 and 7 are such that one half their sum is a perfect number. Are there any other twin primes with this property? It works for p=5. I think it should be of the form 1/2*(p+P+2). Is this true? How can I prove it? Thx
