i need help in solving the question

Let g be a differentiable function such that 9(3) 2 2 and g\" [3) = %J The graph of g is concave down on the interval (2, 4). which of the following Is true about the approxlmatlon for 9(215) found using the line tangent to the graph of g at a: = 3 '3 9 (2.6} m 1.7 and this approximation Is an overestimate of the value of g{2 .]. g(2.6} m 1.7 and this approximation Is an underestimate ofthe value ofg(2.6}. 9 (2.6} m 2.3 and this approximation Is an overestimate of the value of g{2 .]. 6) g (2.6} m 2.3 and this approximation Is an underestimate of the value of g(2.6). f(x) -4 -9 5 4 -7 A 6 2 7 -3 10 -2 3 The table above gives values of the differentiable functions fand g, and f' , the derivative of f, at selected values of x. If g (x) = f 1 (x) , what is the value of g' (4) ? A B C 3 100 D E
