Warm-up – April 1, 2013
• Construct an x-y table and graph for each:
• 1. f(x) = 2x -3• 2. g(x) = x2 + 1• 3. g(x) = x2 + x + 1• 4. g(x) = x3 - 1
Interactive Notebook
p31 MCC912.A.REI.1 Explain each step in solving a simple equation as following from the equality of numbers asserted at the previous step, starting from the assumption that the original equation has a solution. Construct a viable argument to justify a solution method.
P33 MCC912.A.REI.3 Solve linear equations and inequalities in one variable, including equations with coefficients represented by letters.
Angle
• A shape, formed by two lines or rays diverging from a common point (the vertex).
The angle is
ABC
Circle
• The set of points on a plane at a certain distance, or radius, from a single point, the center
Perpendicular Line Two lines that intersect at a right angle (90°).Written as AB PQ

Parallel Line
Lines in a plane that either do not share any points and never intersect, or share all points.Written as AB PQ

Line Segment
A line with two endpoints.Written as
AB
Point
Point A or
Point B
An exact position or location in a given plane.
Line The set of points between points P and Q in a plane and the infinite number of points that continue beyond the points.Written as 67777777777777 7
AB
Distance along a line
The linear distance between two points on a given line.
Right Angle
An angle that measures 90°.
One-to-One A relationship wherein each point in a set of points is mapped to exactly one other point.
Rigid transformations can also be referred to as an ISOMETRY.
Every segment is congruent to its image.
Transformations are called RIGID if every image is congruent to its preimage.
AlgebraicallyAlgebraicallyA function is even if
A function is odd if
All of the exponents of the variable are even.
All of the exponents of the variable are odd.
A function is neither ifThe exponents are a mixture of odd and
even
GraphicallyGraphically
A function is even if
A function is odd if
The graph reflects across the y-axis (means you can fold it hotdog style and it would match up).
The graph has 180 rotational symmetry about the ORIGIN (means you could turn it upside-down & it would still look the same...it must go through the origin).
