Discrete Mathematics With Applicationsa. Use the definition of logarithm to show that log b b x = x for every real number x . b. Use the definition of logarithm to show that b log b x = x for every positive real number x . c. By the result of exercise 28 in Section 7.3. if f : X → Y and g : Y → X are functions and g ∘ f = I X and f ∘ g = I Y , then f and g are inverse functions. Use this result to show that log b and exp b , (the exponential function with base b) are inverse functions.BuyFind*arrow_forward*
