Asked by Michelle
The altitude attained by a model rocket t seconds into flight is given by the equation:
-t^3+3t^2+20t-3 where t is greater than or equal to 0 seconds. find the maximum altitude attained by the rocket.
first I found the derivative of the original equation and set it to 0. which comes out to be -3t^2+6t+20=0. Since this can't be factored what are the next steps?
Thank you!
