Overview:

In this program, students learn about finding values for elements in the domain of quadratic functions, defined as the group of all x values or all inputs.

Content Standard(s):

Mathematics
MA2019 (2019)
Grade: 8

13. Determine whether a relation is a function, defining a function as a rule that assigns to each input (independent value) exactly one output (dependent value), and given a graph, table, mapping, or set of ordered pairs.

Unpacked Content

Evidence Of Student Attainment:

Students:

Define a function as a rule assigning each input exactly one output.
Identify functions when given a relation as graph, table of values, mapping, or set of ordered pairs.

Teacher Vocabulary:

Relation
Function
Input
Output

Knowledge:

Students know:

how to interpret a graph, table, mapping, and ordered pairs.

Skills:

Students are able to:

give an accurate definition of a function.
Analyze graphs, tables, mappings, and sets of ordered pairs to determine if a relation is a function.

Understanding:

Students understand that:

Functions assign every input one output, but they may see outputs repeat.

Diverse Learning Needs:

Essential Skills:

Learning Objectives:
M.8.13.1: Define function, ordered pairs, input, output.
M.8.13.2: Demonstrate how to plot points on a Cartesian plane using ordered pairs.
M.8.13.3: Recall how to complete input/output tables.
M.8.13.4: Recognize numeric patterns.
M.8.13.5: Given a function, create a rule.

Prior Knowledge Skills:

Define quadrant, coordinate plane, coordinate axes (x-axis and y-axis), horizontal, vertical, and reflection.
Demonstrate an understanding of an extended coordinate plane.
Draw a four-quadrant coordinate plane.
Draw and extend vertical and horizontal number lines.
Interpret graphing points in all four quadrants of the coordinate plane in real-world situations.
Recall how to graph points in all four quadrants of the coordinate plane.
