An invertible function f(x) is given along with a point that lies on its graph. Using Theorem 2.7.1 (p. 123 of APEX Calculus v.4), evaluate (f-1)'(x) at the indicated value. f(x) = 5x + sin(5x), 10 Point = TT 10 30' , 1.0236) (f-1)'(1.0236)f(a) = 202 - 17x + 86, x > 8.5, Point = (11, 20) ( f-1)'(20) IDetermine whether the function below is its own inverse. f(f(9=)) =l W Conclusion: the inverse of itself. is is not
