Reflections Across the Y-Axis: f(-x)
For the parent function , the reflection across the y-axis is . Key formulas include expressions such as f(x) = x^2. This concept is part of Big Ideas Math, Algebra 2 for Grade 8 students, covered in Chapter 2: Quadratic Functions.
Key Concepts
For the parent function $f(x) = x^2$, the reflection across the y axis is $f( x) = ( x)^2 = x^2$.
In general, replacing $x$ with $ x$ in any function creates a reflection across the y axis.
