# Access Point #: MAFS.912.F-LE.2.AP.5a

Describe the meaning of the factors and intercepts on linear and exponential functions.
Clarifications:

#### Essential Understandings

Concrete:

• Identify the input value (e.g., x) of a function f(x) (e.g., in f(x) = 3x, the function takes the input x, multiplies it by three, then gives that out as the output).
• Describe the rate of change qualitatively (e.g., steep = rapid rate of change).
Representation:
• Interpret/define a linear equation in terms of slope and y-intercept.
• Interpret/define an exponential function in terms of slope and y-intercept.
• Identify coordinates (points) on a graph.
• Understand the following concepts and vocabulary: x-axis, y-axis, x-intercept, y-intercept, line, rise, fall, slope, rate of change.
General Information
Number: MAFS.912.F-LE.2.AP.5a
Category: Access Points
Cluster: Interpret expressions for functions in terms of the situation they model. (Algebra 1 - Supporting Cluster) (Algebra 2 - Additional Cluster)

Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.
