Calculus limits help?

the function is d(t) = -6t^4 + 7t^2 - 3

How do I find the average velocity for the closed interval [0,3]

Average velocity is the total distance divided by time. Net displacement is d(0)-d(3)

d(3)=-426 d(0)=-3 So total displacement is -3- -426 = 423. Total time is 3 seconds, so 423=3 = 141 d's/second. You didn't list your units so I'm assuming seconds, and d would be your units of distance.
