Answer the following given the function h(r) = 2x - 5. (i) Determine h -1(x). (ii) Use your answer from part(i) to show that (hoh -1) (x) = r. (iii) Use your answer from part(i) to show that h -'(h(r)) = r. (iv) Explain why part (ii) and part (iii) verify the result of part (i). Perform the indicated operations using the following functions. Be sure to simplify your final answer. f(I) =12 -3 g() =1+1 V - (i) (f + g) (I) = a. 13 - 3 (ii) (f - g)(z) = b.
