Mathematics: Functions

In Functions, instructional time should focus on developing the concept of a function in terms of three main areas: (1) developing students’ ability to recognize functions and how they can be represented in multiple formats; (2) building functions to model a relationship between two quantities; (3) introducing students to several different types of functions including linear, quadratic, exponential, and trigonometric functions and helping students distinguish when to use a given function type to model a particular situation.

F.IF - Interpreting Functions

Analyze functions using different representations
Code
Standard
Concepts
F.IF.7a
Graph linear and quadratic functions and show intercepts, maxima, and minima.
3
F.IF.7b
Graph square root, cube root, and piecewise-defined functions, including step functions and absolute value functions.
2
F.IF.7c
Graph polynomial functions, identifying zeros when suitable factorizations are available, and showing end behavior.
2
F.IF.7d
(+) Graph rational functions, identifying zeros and asymptotes when suitable factorizations are available, and showing end behavior.
6
F.IF.7e
Graph exponential and logarithmic functions, showing intercepts and end behavior, and trigonometric functions, showing period, midline, and amplitude.
11
F.IF.8a
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.
2
F.IF.8b
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.
