the function f is twice differentiable,and the graph of f has no points of inflection.if f(6)=3,f'(6)=-1/2,and f''(6)=-2,which of the following could be the value of f(7)?a.2 b.2.5 c.2.9 d.3 e.4有没有合理的解释?

several values of the function f are shown. the function g is defined by g(x)=f(3x+1).what is the value of g(2) What is the slope of the line whose function f satisfies f(-2)=1 and f(5)=-10? what is the image of the function f:R->R,f|x|+x?use the interval notation what is the value of the discriminant for the function f(x)=8x^2+13x+7? A portion of the graph of the function f is shown in the xy-plane above. What is the y-intercept ofthe graph of the function g defined by g(x)=f(x)+1? Yes ,there's re tw .One is big .The other is small . 关于一题SAT数学题If f(x)=x^3+1 and of f^(-1)（x) is the inverse function of f,what is f^(-1)(4)? 答案是1.44 求详细解答! 谢谢谢!inverse function 是什么? several values of the function f are shown above.the function g is defined by g(x)=f(3x+1)what is the value of g(2)? 英语翻译Feedback on the effectiveness of the internal audit function is also important.While research is limited in this area,it has unequivocally demonstrated that the internal audit function is most effective when it has independence （in “f the function f is defined by f(X)=cosec x + tan2x ,A.show that the roots of f(x)=0 satisfy the pls solve the function f is defined by f(X)=cosec x + tan2x ,A.show that the roots of f(x)=0 satisfy the equation2cos^3 (x) -2cos^2(X)-2cosx+1=0 if f is the function given by f(x)=∫√t^2-t dt,(4→2x)then f'(2)= Given the function f(x) = 150,what is the value of f(10)?a.10b.150c.160d.1500为什么 ..thanks a lot . 英语翻译the graph of the function f is shown in the xy-plane above.When the graph of f is reflected about the x-axis,the result is the graph of the function g.What is the value of g(2)? 英语翻译Find all zeroes of these functions,and any values of x where the function is discontinuous.Then analyse the sign of the function by taking test points around these zeroes and discontinuities.f(x)=x/(x-3) what is the social function of the language what is the function of the first paragraph什么意思 what is the function of the reception area? The future is a function of the past.
