<span>Answer: year 0 you get 3 * .25^0 = 3 * 1 = 3 year 2 you get 3 * .25^1 = 3 * .25 = .75 year 3 you get 3 * .25^2 = 3 * .0625 = .1875 the numbers are decreasing year after year so you are talking about decay. b^x increases as x increases if b is greater than 1. b^x stays the same as x increases if b is equal to 1. b^x decreases as x increases if b is greater than 0 and less than 1. x is assumed to be greater than or equal to 0.</span>

Composition of the function is commuatative

dimulka [17.4K]

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.

Why is a table proportional?

krek1111 [17]

Determining whether two quantities are in a proportional relationship. Decide whether two quantities are in a proportional relationship, e.g., by testing for equivalent ratios in a table or graphing on a coordinate plane and observing whether the graph is a straight line through the origin.
