Find f'(x) and find the equation of the line tangent to the graph of f at the indicated value of x. Find the value(s) of x where the tangent line is ho f ( x ) = In (1 -x2 +2x4) ; x=1 f' (x) = The equation of the line tangent to the graph of fat x = 1 is y =]. Select the correct choice below and fill in any answer boxes in your choice. O A. The value(s) of x where the tangent line is horizontal is/are (Simplify your answer. Use a comma to separate answers as needed.) O B. The tangent line is never horizontal.The demand x is the number of items that can be sold at a price of $p. For X: p4 5p + 1200, find the rate of change of p with respect to x by d E> The rate of change of the price p with respect to the demand x is D. dx = -6, X= 3, y= - 3. Assume x and y are functions of t. Evaluate - for 3xy - 5x + 3y = - 123, with the conditions - dy dt (Type an exact answer in simplified form.)Find the relative rate of change of f(x) at the indicated value of x. f(x)=297-3x;x=18 E> The relative rate of change of f(x) at X: 18 is E. (Type an integer or decimal rounded to three decimal places as needed.) Use the price-demand equation to find E(p), the elasticity of demand. x= f(p) = 185 - 60 In (p) E(p) =
