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.A.2 – Use function notation, evaluate functions for inputs in their domains, and interpret statements that use function notation in terms of a context.
HSF.IF.B.5 – Relate the domain of a function to its graph and, where applicable, to the quantitative relationship it describes.
- 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.12(B) – evaluate functions, expressed in function notation, given one or more elements in their domains
