Quizplus · Accepted Answer

From the contour diagram, we can see that the contour lines for f_x are spaced out by intervals of 3. The difference between the contour line passing through 11eb69ff_fdfd_aec7_af94_fffff905c485_TB8190_11 (which is labeled as -3) and the contour line passing through 11eb69ff_fdfd_aec8_af94_7947f3f5db52_TB8190_00 is 6. This means that _{has changed by 2 units (from 11 to 00) while} has remained constant. Therefore, the estimate for f_x at the point 11eb69ff_fdfd_aec6_af94_8f9a3e43bdcd_TB8190_11 (which is in between the two points given) is 3.
