The closest answer would be B $12.69.
Answer: The function shows by the table is cubic function.
Explanation: Since, the given values of the function are
f(x): –29 –10 –3 –2 –1 6 25
First difference: 19 7 1 1 7 19
Second difference: -12 -6 0 6 12
Third difference: 6 6 6 6
Since, here, the value in third difference is repeating to 6. Therefore, according to the definition of successive difference, equation must have three degree. So, it is a cubic equation.
First you have to do 12x1200 then the answer is 9999
