Consider the curves in the xy-plane for each problem. At the point given point, is the curve increasing or decreasing? Justify your answer.
3. 3=3x^(2)-y^(2) at (2,-3)
4. cosy=x^(2)-4 at (2,(pi )/(2))
5. lny=x^(2)-5 at (sqrt(5),1)
5. 1n y= x2 - 5 at (v5,1)
3.3=3x2 -y2at(2,-3 decreasing?Justify your answer.
