Unit 9 Vocab

linear function

• y = x

• using f(x) instead of y

• the point(s) where the graph crosses the x-axis. The ordered pair (a, 0)

• A flipping movement caused by multiplying or dividing INSIDE the parenthesis. The flip is over the y-axis

function notation

• y = x

• using f(x) instead of y

• the point(s) where the graph crosses the x-axis. The ordered pair (a, 0)

• A flipping movement caused by multiplying or dividing INSIDE the parenthesis. The flip is over the y-axis

x-intercept

• y = x

• using f(x) instead of y

• the point(s) where the graph crosses the x-axis. The ordered pair (a, 0)

• A flipping movement caused by multiplying or dividing INSIDE the parenthesis. The flip is over the y-axis

horizontal reflection

• y = x

• using f(x) instead of y

• the point(s) where the graph crosses the x-axis. The ordered pair (a, 0)

• A flipping movement caused by multiplying or dividing INSIDE the parenthesis. The flip is over the y-axis

transformations

• All shrink, stretches, translations, and reflections done both horizontally and vertically to a graph.

• The most basic graph of a function without any transformations. A family of graphs with the same characterisics

• An up or down movement caused by adding or subtracting OUTSIDE the parenthesis. The movement is the same as the sign.

• A left or right movement caused by adding or subtracting INSIDE the parenthesis. The movement is the opposite of the sign.

parent function

• All shrink, stretches, translations, and reflections done both horizontally and vertically to a graph.

• The most basic graph of a function without any transformations. A family of graphs with the same characterisics

• An up or down movement caused by adding or subtracting OUTSIDE the parenthesis. The movement is the same as the sign.

• A left or right movement caused by adding or subtracting INSIDE the parenthesis. The movement is the opposite of the sign.

vertical translation

• All shrink, stretches, translations, and reflections done both horizontally and vertically to a graph.

• The most basic graph of a function without any transformations. A family of graphs with the same characterisics

• An up or down movement caused by adding or subtracting OUTSIDE the parenthesis. The movement is the same as the sign.

• A left or right movement caused by adding or subtracting INSIDE the parenthesis. The movement is the opposite of the sign.

horizontal translation

• All shrink, stretches, translations, and reflections done both horizontally and vertically to a graph.

• The most basic graph of a function without any transformations. A family of graphs with the same characterisics

• An up or down movement caused by adding or subtracting OUTSIDE the parenthesis. The movement is the same as the sign.

• A left or right movement caused by adding or subtracting INSIDE the parenthesis. The movement is the opposite of the sign.

absolute value function

• y = |x|

• A relation where there is only one y for every x

• The point(s) where the graph crosses the y-axis. The ordered pair (0, a)

• A line that the graph approaches but never reaches.
