Question
Determine the domain and range of the given functions. Then sketch the contour plot
of function using 3 level curves.
1
f (x, y) = Jay2 + cx² + 3(a + c)
where
a - The last digit of your matrix number
For example, a student with the matrix number CD20008 will have the values of c
= 8. Use 1 if the last digit is of your matrix number is 0.
Zero marks will be given without showing the steps for solution.
Sketch the domain and three-dimensional (3D) graph in first quadrant of the
following function:
z? = -ay? – cx? + 8c
(b)
where
a - The first digit of your matrix number
c- The last digit of your matrix number
For example, a student with the matrix number CD200008 will have the values of a
= 2 and c = 8. Use 1 if the last digit is of your matrix number is 0.
Zero marks will be given without showing the steps for solution.
(c)
Determine whether the following function continuous at point (0, 0). Justify your
answer.
if (x, y) # (1,1)
f (x, y) :
if (x, y) = (1,1)
Zero marks will be given without showing the steps for solution.
