Study Notes
Parent Functions
-
Constant Function (P-Function):
- Defined by f(x) = c
- Graph is a straight line
- Domain is all real numbers (R)
- Range is a single value: y = c
- Intersects Y-axis at point (0, c)
-
Linear Function (P-Function):
- Defined by f(x) = x
- Graph is a diagonal line through the origin
- Domain is all real numbers (R)
- Range is all real numbers (R)
- Intersects at point (0, 0)
-
Quadratic Function (P-Function):
- Defined by f(x) = x²
- Graph is a parabola opening upwards
- Domain is all real numbers (R)
- Range is y > 0
- Intersects at point (0, 0)
-
Cubic Function (P-Function):
- Defined by f(x) = x³
- Graph consists of two halves of a parabola
- Domain is all real numbers (R)
- Range is all real numbers (R)
- Intersects at point (0, 0)
-
Square Root Function (P-Function):
- Defined by f(x) = √x
- Graph shows an upward slope
- Domain is x > 0
- Range is y > 0
- Intersects at point (0, 0)
Helpful Tips
-
Identifying Parent Functions:
- A greater number of data points improves the accuracy of matching to a parent function.
-
Transforming Linear Functions:
- For translations: "Add to y, go high; Add to x, go left."
-
Intercept Properties:
- Horizontal stretches/compressions do not affect y-intercepts.
- Vertical stretches/compressions do not affect x-intercepts.
Correlation Coefficient Properties
- The correlation coefficient, denoted as r, ranges from -1 to 1.
