Hi.. :)

Its given that a function is continuous and can take only rational values and f(3) =10
So, it must be the case that f(x) = 10 which is an even function.

@Sinistral:
Constant function is both increasing and decreasing.

@taani:
A rational number is any number that can be expressed as a fraction p/q of two integers, with the denominator q not equal to zero. Since q may be equal to 1, every integer is a rational number.
So, we have odd rational numbers also.
Eg: 3, 5, 7, ....
