Exponentials Functions Vocab - Maritza Suarez

If r is the rate of decay, then the function can be written y=a(1-r)^t, A=initial amount T=time

Closed-form expression, a mathematical expression in terms of a finite numbers

A pattern rule which is used to find the next term.

Interest earned or paid on both the principal and previously earned interest

A formula that is used to determine the next term of a sequence

If r is the rate of growth , then the function can y=a(1+r)^t

A sequence in which the ratio of successive terms is a constant r, called the common ratio

A sequence whose successive terms differ by the same nonzero number d, called the common dif.

The time it takes for one-half of the substance to decay into another substance

In a geometric sequence , the constant ratio of any term and the previous term
