I got a question that i dont know how to answer could someone help:

thanksCode:`Evaluate the gradient of f at the point P, where`

f(x, y, z) = x2yz4, P(-1, 3, -1)

Please enter your answer as a row vector, using thelistsyntax.

when you say gradient do you mean this gradient: :

if that is so then:

since f(x,y,z) is given as:

substituting into (1) gives:

entering the value of x,y,and z into equation (2) gives:
