Suppose That as You Move Away from the Point (2 $0.6 \vec { i } + 0.8 \vec { j }$

Short Answer

Suppose that as you move away from the point (2, 0, 2), the function increases most rapidly in the direction $0.6 \vec { i } + 0.8 \vec { j }$ and the rate of increase of f in this direction is 7.At what rate is f increasing as you move away from (2, 0, 2)in the direction of $\vec { i } + \vec { j } + \vec { k }$ ? Give your answer to 4 decimal places.
