If you are rowing a boat upstream, given the following equation that models your speed: f(x)=3x^2-6x-13, where x is the velocity of the boat relative to land. What is the domain of this function? Normally the domain for parabolas is all real numbers, but in this case, would it be x is greater than or equal to one since speed can't be negative but since x is velocity is that the same?
