Test Review Unit 4

Front

What is the average rate of change between when x = -1 and x = 0?

Back

The average rate of change is calculated as the change in the function value divided by the change in x. For this case, it is -2.

Front

What is the formula for calculating depreciation?

Back

Depreciation can be calculated using the formula: Value = Initial Value * (1 - Depreciation Rate)^Number of Years.

What is the explicit formula for a geometric sequence?

Back

The explicit formula for a geometric sequence is given by: a_n = a_1 * r^(n-1), where a_1 is the first term and r is the common ratio.

Front

What is the common ratio in a geometric sequence?

Back

The common ratio is the factor by which we multiply to get from one term to the next in a geometric sequence.

Front

How do you find the value of a depreciating asset after a certain number of years?

Back

Use the formula: Value = Initial Value * (1 - Depreciation Rate)^Number of Years.

Front

What does it mean for a sequence to be geometric?

Back

A sequence is geometric if each term after the first is found by multiplying the previous term by a fixed, non-zero number called the common ratio.

Front

What is the formula for the nth term of a geometric sequence?

Back

The nth term can be found using: a_n = a_1 * r^(n-1).
