# Access Point #: MAFS.912.F-BF.2.AP.3a

Write or select the graph that represents a defined change in the function (e.g., recognize the effect of changing k on the corresponding graph).
Clarifications:

#### Essential Understandings

Concrete:

• Identify the y-intercept on a graph.
• Given the graph of the new and parent functions, describe the change when k is introduced.
• Use graphing software to discriminate between skinny and wide graphs (k f(x)).
• Use graphing software to discriminate directionality (right/left) (f(x + k) ) (up/down) f(x) + k.
Representation:
• Identify the y-intercept in a function.
• Identify k in a function (f(x) = x + 5), k = 5.
• Given a graphic template, predict the changes k will have on the function.
• Describe the effects k has on a given equation.
• Understand the coordinate plane.
• Understand related vocabulary (y-intercept, y-axis, x-axis, function, positive, negative, k, translation, function, stretch, shrink, quadratic function, exponential function).
General Information
Number: MAFS.912.F-BF.2.AP.3a
Category: Access Points
Cluster: Build new functions from existing functions. (Algebra 1 - Additional 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.
