Domain & Range / Solving Inequalities Re-engage

50 Minute Class, Algebra 1, Curriculum

Learning Goals: (1)Develop the ability to determine the Domain and Range for linear functions (2)Solidify conceptual and procedural understanding of solving inequalities.


Re-Engage:

Classwork:


Standards:

  • Common Core
    • HSF.IF.A.1 – Understand that a function from one set (called the domain) to another set (called the range) assigns to each element of the domain exactly one element of the range. If f is a function and x is an element of its domain, then f(x) denotes the output of f corresponding to the input x. The graph of f is the graph of the equation y = f(x).
    • HSF.IF.B.5 – Relate the domain of a function to its graph and, where applicable, to the quantitative relationship it describes.
    • HSA.REI.B.3 – Solve linear equations and inequalities in one variable, including equations with coefficients represented by letters.
  • TEKS (2015-16)
    • A.2(A) – 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
    • A.5(B) – solve linear inequalities in one variable, including those for which the application of the distributive property is necessary and for which variables are included on both sides
