Rate of Change

Interpreting rate of change from given real-world model, creating an exponential model from given rate of change.

Mapped to CCSS Section# HSA.SSE.B.3c, HSF.LE.A.1b

Use the properties of exponents to transform expressions for exponential functions. For example the expression 1.15t can be rewritten as (1.151/12)12t ≈ 1.01212t to reveal the approximate equivalent monthly interest rate if the annual rate is 15%. Recognize situations in which one quantity changes at a constant rate per unit interval relative to another.
