    What is the difference between A-SSE.3c and F-IF.8b?

    A-SSE.3 Choose and produce an equivalent form of an expression to reveal and explain properties of the quantity represented by the expression.
    c. Use the properties of exponents to transform expressions for exponential functions. For example the expression 1.15t can be rewritten as (1.151/12)12 t ≈ 1.01212t to reveal the approximate equivalent monthly interest rate if the annual rate is 15%.

    F-IF.8 Write a function defined by an expression in different but equivalent forms to reveal and explain different properties of the function.
    b. Use the properties of exponents to interpret expressions for exponential functions. For example, identify percent rate of change in functions such as y = (1.02)t, y = (0.97)t, y = (1.01)12t, y = (1.2)t/10, and classify them as representing exponential growth or decay.

    It seems like all of the questions I have seen could fall under either standard.

    To me it looks like A.SSE.3c is after transforming an expression for the purpose of revealing something about a particular quantity (which is represented by the expression), whereas F.IF.8 is focused on revealing properties of a function – like whether the function represents exponential growth or decay. In short – a single quantity versus a function.
