What is a function in mathematics?

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 can you determine if a graph represents a function?

Back

You can use the vertical line test: if a vertical line intersects the graph at more than one point, it is not a function.

Front

What does the notation (x + 2, y - 1) represent in transformations?

Back

It represents a translation of the graph 2 units to the left and 1 unit down.

Front

What is the y-intercept of a graph?

Back

The y-intercept is the point where the graph crosses the y-axis, represented as (0, y).

Front

What does it mean for a relationship to be proportional?

Back

A relationship is proportional if it can be represented by a straight line through the origin (0,0) and has a constant ratio between the variables.

Front

What is the measure of a right angle?

Back

A right angle measures 90 degrees.

Front

What is the sum of angles in a triangle?

Back

The sum of the interior angles in a triangle is always 180 degrees.

Front

What is a non-proportional relationship?

Back

A non-proportional relationship does not have a constant ratio and does not pass through the origin.

Front

How do you find the expected number of participants in a scenario?

Back

You can use ratios or proportions based on given data to estimate the expected number.

Front

What is the definition of translation in geometry?

Back

Translation is a type of transformation that moves every point of a shape the same distance in a specified direction.
