MAFS.912.F-IF.3.8 – Write a function defined by an expression in different but equivalent forms to reveal and explain different properties of the function.
- The benchmark will be assessed using Drag and Drop Response, Equation Response, Graphic Response, Hot Spot Response, Multi-select Response, Multiple Choice Response or Open Response.
- Items may require students to factor or complete the square in a quadratic function to show zeroes, extreme values, and symmetry of the graph.
- Items may require students to use the properties of exponents to interpret expressions for exponential functions.
- Items may require students to identify zeroes, asymptotes, end behavior, and characteristics of trig functions (period, midline, amplitude and phase shift).
- Functions may also include square root, cube root, piecewise-defined functions, step functions, and absolute value functions.
