Let fix) = 3x - 5x -3, x2 1.5. Find the value of at the point x = 465 = f(6). dx df 1 The value of at the point x = 465 = f(6) is x (Type a simplified fraction.)Suppose that the differentiable function y= f(x) has an inverse, that the graph of f passes through the point (1,4), and it has a slope of - at that point. Find the value of of at x =4. - - . of dx x = 4 =(Type an integer or a simplified fraction.)
