Say you have the function x=2t^2-6t, would the distance traveled for the first 3 secs be the integral of the function from [0.3]

not at all. That is the displacement equation.

You will only get the distance if you find the integral of the velocity equation from [0,3]

make sure to always graph the velocity vector. In this case you need to take the negative of the integral as its below the x axis for the interval [0,3]
