Front

Define depreciation in the context of algebra.

Back

Depreciation is the reduction in the value of an asset over time, often expressed as a percentage.

Front

What is an exponential function?

Back

An exponential function is a mathematical function of the form f(x) = a(b)ⁿ, where 'a' is a constant, 'b' is the base, and 'n' is the exponent.

Front

How do you calculate the value of an asset after 'n' years of depreciation?

Back

Value = Initial Value × (1 - Depreciation Rate)ⁿ

Front

What is the formula for finding the sum of two polynomials?

Back

Add the coefficients of like terms together.

Front

What is the difference between linear and exponential growth?

Back

Linear growth increases by a constant amount, while exponential growth increases by a constant percentage.
