Which ordered pair is the best approximation of the exact solution?

For this case what you should do is observe the table that the values of y of both functions are as similar as possible.
 We observed that:
 For the x 1.6 coordinate we have:
 
 Therefore, a good approximation of the solution is:
 
 The ordered pair solution is:
 (1.6, 1.3)
 
 (1.6, 1.3)option A

Is 8.50 an answer or no? ?
