Suppose that $T ( x , y ) = x ^ { 2 } + 3 y ^ { 2 } - x$ is the temperature (in degrees Celsius)at the point $( x , y )$ (where x and y are in meters).If you are standing at the point $( - 2,1 )$ and proceed in the direction of the point $( - 6 , - 3 )$ , will the temperature be increasing or decreasing at the moment you begin? At what rate? Give your answer to 4 decimal places.

The Answer of Suppose that $T ( x , y ) = x ^ { 2 } + 3 y ^ { 2 } - x$ is the temperature (in degrees Celsius)at the point $( x , y )$ (where x and y are in meters).If you are standing at the point $( - 2,1 )$ and proceed in the direction of the point $( - 6 , - 3 )$ , will the temperature be increasing or decreasing at the moment you begin? At what rate? Give your answer to 4 decimal places.

Suppose That T(x,y)=x2+3y2−xT ( x , y ) = x ^ { 2 } + 3 y ^ { 2 } - xT(x,y)=x2+3y2−x
