Perhaps your derivative is wrong
Using the quotient rule, I got a derivative of
-4t(t^3 - 8)/(4+t^3)^2
setting that to zero gave me
t - 2 or t = 0
for the given domain, t=2
v(2) = 16/12 = 4/3
An object moves in a straight line. Its velocity, in m/s, at time t is v(t)=4t^2/(4+t^3), t>(greater or equal)0. Determine the maximum and minimum velocities over time interval 1<t<4
I got minimum as 1= 4/5. However for maximum at t=4, I got 16/17 but the book says 4/3?
