# 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
