Reflection Across X-Axis: y = -f(x)
To reflect a function across the x-axis, replace with : Key formulas include expressions such as f(x). This concept is part of Big Ideas Math, Algebra 2 for Grade 8 students, covered in Chapter 1: Linear Functions.
Key Concepts
To reflect a function across the x axis, replace $f(x)$ with $ f(x)$: $$y = f(x)$$.
This transformation multiplies every y coordinate by $ 1$ while keeping x coordinates unchanged.
