Assume that the given function has an inverse function. 15. Given f(3) = 7, find f'(7) 16. Given f'(-3)=-4, find f(-4) 17. The domain of the inverse function f is the of f. the 18. The range of the inverse function f' is of f. Use composition of functions to determine whether f and g are inverses of one another. 19. f(x)=4x; g(x)=1 20. f(x)=x-; g(x)=2x+3 f(x)==11x- 3 2 21. f(x) ==--12x =--x- ; g(x)=-2x+1 22. (x)=3x+2;_g(x)=x/ 2 2
