What is a function?

Back

A function is a relation between a set of inputs and a set of possible outputs where each input is related to exactly one output.

Front

How do you represent a function using a graph?

Back

A function can be represented on a graph where the x-axis represents the input values and the y-axis represents the output values. A vertical line test can be used to determine if a graph represents a function.

What does it mean for a relationship to be proportional?

Front

What is a translation in geometry?

Back

A translation is a transformation that moves every point of a figure the same distance in a specified direction.

Front

What is the rule for translating a point 2 units to the right and 3 units down?

Front

What is dilation in geometry?

Back

Dilation is a transformation that changes the size of a figure but not its shape, using a center of dilation and a scale factor.

Front

What is the scale factor in dilation?

Back

The scale factor is the ratio of the size of the image to the size of the original figure. A scale factor greater than 1 enlarges the figure, while a scale factor between 0 and 1 reduces it.

How do you describe a translation of a trapezoid 4 units left and 5 units up?

Back

Front

What is the difference between a translation and a reflection?

Back

A translation moves a figure without changing its orientation, while a reflection flips a figure over a line, creating a mirror image.

What is the formula for a linear function?
