Chapter 3.2
Function notation (advanced)
What You'll Learn
Evaluate functions by substituting values, symbols, and expressions for x
Apply function notation f(x) to represent relationships between variables
Interpret function notation from graphs by matching x-values to y-values
Express algebraic expressions in terms of given function definitions
Simplify complex function expressions involving polynomials and radicals
What You'll Practice
1
Substituting numbers, variables, and expressions into polynomial functions
2
Rewriting square root expressions using function notation
3
Reading function values and coordinates from graphs
4
Finding x-values that produce specific function outputs
Why This Matters
Function notation is the language of advanced mathematics. You'll use f(x) notation in every math course from algebra through calculus, and it's essential for understanding how variables relate in science, engineering, and data analysis.
