Find the gradient of  at

Quizplus · Accepted Answer

The gradient is a vector which gives the direction of the steepest increase of a function at a particular point. To find the gradient, we need to compare the coordinates of two points and calculate the difference between them. In this case, the difference between the second and first sets of digits in each position gives us the gradient vector. Therefore, the correct answer is B as it has a difference of 'f1f3' in the second set of digits compared to 'cd9b' in the first set of digits.
