Given: `g(t)=(t^2)/(t^2+3)[-1,1]`

Find the critical values for t by setting the derivative equal to zero and solving for the t value(s).


` ` `2t^3+6t-2t^3=0`



Plug in the critical t value(s) and the endpoints of the closed interval into the g(t) function.





Examine the g(t) values to determine the absolute extrema.

The absolute maximum is the points are  `(-1, 1/4), (1,1/4).`

The absolute minimum is the point (0, 0).
