Algebra I Unit 2

Big Idea:

Model, represent, and transform functions while identifying key features of graphs and equations.

Student Expectations:

Priority TEKS

A.2(A) [Readiness] determine the domain and range of a linear function in mathematical problems; determine reasonable domain and range values for real-world situations, both continuous and discrete; and represent domain and range using inequalities

Focus TEKS

A.3(C) [Readiness] graph linear functions on the coordinate plane and identify key features, including x-intercept, y-intercept, zeros, and slope, in mathematical and real-world problems

A.3(E) [Supporting] determine the effects on the graph of the parent function f(x) = x when f(x) is replaced by af(x), f(x) + d, f(x – c), f(bx) for specific values of a, b, c, and d

A.12(A) [Supporting] decide whether relations represented verbally, tabularly, graphically, and symbolically define a function

A.12(B) [Supporting] evaluate functions, expressed in function notation, given one or more elements in their domains

Student Learning Targets:

• I will identify the difference between a relation and a function.
• I will represent relations and functions using tables, diagrams, and graphs.
• I will determine and represent the domain and range of a function in mathematical and real-world situations.
• I will evaluate the function given the value of the domain, using function notation.
• I will solve for the domain value given a value of the range of a function, using function notation.
• I will identify and interpret key features of graphs.
• I will identify and describe linear transformations.

Essential Questions:

• Why are functions useful in real-world settings?
• How can you show mathematical relationships?
