Can anyone please help me with this question please? I am stuck! Please help me!

Section 12.1: Problem 12 (1 point) Calculate a Riemann sum $3,3 on the square R = [0, 3] x [0, 3] for the function g(z, y) = f(z, y) - 4. The contour plot of f (x, y) is shown in Figure 4. Choose sample points and use the plot to find the values of f (x, y) at these points. Use the values of f(x, y) to evaluate g(x, y) accordingly. 12 O FIGURE 4 Contour plot of f(I, y) S3.3
