Foundations For Functions
- Properties & Operations
- Interval Notation
- ( ) means closed set
- [ ] means included in set
- Don't include infinity in [ ]
- { } means "set of"
- Operations
- Additive Inverse (opposite on number line)
- Multiplicative Inverse (reciprocal)
- Only if non-zero
- Square Roots
- When Sq. root is in the denominator
undo by mult. by form of 1
- Introduction to Functions
- Relation = pairing of input values w/ output values
- Domain = set of input values (x-coordinates)
- Range = set of output values (y-coordinates)
- Function = relation in which there is only
1 output for each input
- Transformation = Change in position, size, or shape
- Reflection = transformation that
flips figure across line of
reflection
- Compression/stretching = multiply
- Translation = Transformation that moves each
point in a figure same distance in
same direction
- Parent Functions
- A parent function is the simplest function
- f(x)=x cu. ; cubic
- f(x)=c ; constant
- f(x)=x ; linear
- f(x)=sq. root x ; Sq. root
- f(x)= x sq. ; quadratic
