1
Q
absolute max/min
A
- highest/lowest over entire range
- TP for odd dont count
2
Q
odd functions: TP and x-int
A
TP: 0 → n-1
x-int: 1→n
3
Q
even functions: TP and x-int
A
TP: 1 → n-1
x-int: 0 → n
4
Q
end behaviours of odd functions (pos nd neg) quadrant-wise
A
even: Q3 → Q1
odd: Q2 → Q4
5
Q
where are max/min on odd functions
A
none
6
Q
properties of even degree functions in vertex form
A
- vertex: (d, c)
- axis of symm: x=d
- max/min: y=c
7
Q
secant line
A
line that intersects curve at two distinct points
8
Q
tangent line
A
line that touches curve at one point, has slope at that point
9
Q
when do u use DLEXY vs mapping notation?
A
- mapping notation: a(k(x-d))+c form (transformed form)
- DLEXY: a( )( ) form (x-intercept form)
