HSF.IF.A.2

**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.A.2: Use function notation, evaluate functions for inputs in their domains, and interpret statements that use function notation in terms of a context.

What you'll learn

Evaluate functions at numeric inputs by substituting values into function rules, including negative numbers and fractions
Evaluate functions at expression inputs such as f(a + 1), f(2x), and f(x + h), correctly applying substitution and simplifying
Interpret function notation statements like f(3) = 7 or f(a) = f(b) in terms of a real-world context, going beyond restating the notation
Solve equations of the form f(x) = c by finding the input(s) that produce a given output
Read and evaluate function values from tables and graphs, not just from algebraic formulas
Distinguish between compound expressions like f(a + b) and f(a) + f(b), recognizing they are generally not equal
