HSF.IF.C.8

Standard

Write a function defined by an expression in different but equivalent forms to reveal and explain different properties of the function.

Sub-standards

• HSF.IF.C.8.a — Use the process of factoring and completing the square in a quadratic function to show zeros, extreme values, and symmetry of the graph, and interpret these in terms of a context.
• HSF.IF.C.8.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)12^t, y = (1.2)^t/10, and classify them as representing exponential growth or decay.
