Standard Forms (p.1)

Straight Line

Ax + By + C = 0
Parallel Lines
Perpendicular Lines
Ordered Pairs

eg.
Function Notation

eg.
differentiate FUNCTION and RELATION
- Function: 1x for 1y
- Relation: 1x for 2 ys
a function is a rule that associates 1 x to 1 y.
rule for square route functions
eg.

(cannot be negative!)
rule for fraction functions
eg.

denominator cannot be 0! (solve for x)
LINEAR
eg. OR

diagonal!
CONSTANT
eg. OR

straight horizontal line
QUADRATIC
eg.

parabola!
CUBIC
eg.

squiggly diagonal!
ABSOLUTE VALUE
eg.

straight V shape!
SQUARE ROUTE
eg.

half of sideways parabola!

(hill)
CIRCLE
eg. OR

well, a circle.
SEMI-CIRCLE
eg. or

semi-circle.
when is a function increasing?

when whenever .
What happens to a quadratic formation when...

the VERTEX moves up 1
What happens to a quadratic formation when...

see what makes x = 0.

that number is the vertex. (eg, x = +2)
how to find y-int of a function?

let x = 0
the standard form of a quadratic function is .

what is the VERTEX form?
- vertex form:
what happens to range and domain when a function has or ?
- solve it normally, it makes no difference.
- (except with 3 the numbers can stay negative)
what happens when you take the squared off of and apply it to the 2?
- it becomes
- (if you make it your own square route)
how do you find the MAX or MIN of a function?

take the Y value at its max or minimum point. eg, y = -8.
how do you go from standard form to vertex form ?

complete the square!

so...
how do you find the vertex from form?
