40. 24+26=50 41. I don't understand that one either what grade are you in?
Answer:
The functions g and f are said to commute with each other if g ∘ f = f ∘ g. Commutativity is a special property, attained only by particular functions, and often in special circumstances. For example, |x| + 3 = |x + 3| only when x ≥ 0. ... The composition of one-to-one functions is always one-to-one.

<span>Amount spent at start C = $300
Rate = 3% = 0.03
Number of periods = 3 years
Future Value at the maturity FV = 300 x (1 + 0.03) ^3= 300 x 1.0927 = 328
The correct answer would be 328.14</span>
