1.4. Relate y = f(x) and y = |f(x)|
- Understand the relationship between y = f(x) and y = |f(x)| where f(x) may be linear, quadratic, cubic or trigonometric.
- For trigonometric functions, use y = a sin bx + c, y = a cos bx + c or y = a tan bx + c, where a is a positive integer, b is a simple fraction or integer, and c is an integer.
- Fractions for b have denominator 2, 3, 4, 6 or 8 only.
