Best ResponseYou've already chosen the best response.1g(x) is not clear,because there is no indication what kind of nonlinear function it is. IF it is assumed to be a quadratic (defined by three given points), then you can work back to get f(0) by forward differences. dw:1439301717122:dw

Best ResponseYou've already chosen the best response.1For a quadratic, the second difference is constant. so if we tabulate the differences, we can work out g(0).

Best ResponseYou've already chosen the best response.1I totally agree that it is a horrible question, which we see very often in multiple choice questions. Unfortunately today math does not teach students to be rigorous, but instead, (incorrectly in math ) to generalize.

Best ResponseYou've already chosen the best response.1If it is cubic, it is NOT defined by three points. If it is quadratic, there is only one quadratic that passes through all these points.

Best ResponseYou've already chosen the best response.1IF it is a quadratic, then we can use the following table to work it out. Unfortunately with a multiple choice, you cannot support your answer in any way. That is why multiple choice questions are frustrating when the question is not properly made.

Best ResponseYou've already chosen the best response.1IF it is a quadratic, we can work backwards: dw:1439302374183:dw to conclude that g(0)=33
