Can someone help me out with this?

Practice 1 Below are four pairs of functions. Three of the pairs are inverse functions, one pair is not. Find the pair that are not inverse functions, and prove that the other three pairs are inverse functions. A. f (x) = ;9(x) = 4x +9 B. f(x) = Vx - 8:9(x) =8+x2 C. f (x) = : g(x) = 1x D. f (x ) = *-1. * +5 ; 9 ( x ) = - - 5x + 1 x - 1 Practice 2 For each function below, find the inverse.. f(x) = x-5 g (x) = x+3 h(x ) = 4 - -x i(x) = 6Practice 3 For each function, determine if it is one-to-one. If it is, find the inverse. If it is not one-to-one, find the restricted domain that will result in a one-to-one function. g ( x) = 1x + 71 h ( x) = (x - 3) 1(x) = 31x + 51 Practice 4 For each pair of functions, find (f . g)(x) A. / (x) = 4x - 3:9(x) = 3x +4 B. f (x) = x + 3; 9(x) = 2x - 1 Practice 5 The graph of h is shown at left. A. Is h a function? How do you know? B. Is h a one-to-one function? How do you know? C. Find h ( 2 ) D. Find h (- 2) Practice 6 To convert from degrees Fahrenheit to degrees Celsius, we can use the equation C = = (F - 32) . A. Write the inverse of this function B. What does the inverse function represent
