# 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 1yRelation: 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?
