Unit 2 Show Me What You Remember

Front

State whether or not the relation is a function.

Back

A relation is a function if each input (x-value) has exactly one output (y-value).

Front

y -intercept is where the line ______________.

Back

crosses the y-axis.

Front

What is the standard form of a line?

Back

Ax + By = C, where A, B, and C are constants.

Front

Which graph does NOT pass the vertical line test?

Back

A graph that has at least one vertical line that intersects it at more than one point is not a function.

Front

Identify the mapping diagram that represents the relation and determine whether the relation is a function: {(−8, −6), (−5, 2), (−8, 1), (7, 3)}

Back

This relation is not a function because the input -8 has two different outputs (-6 and 1).

Front

What is a function?

Back

A function is a relation that assigns exactly one output for each input.

Front

What is the domain of a function?

Back

The domain is the set of all possible input values (x-values) for the function.

Front

What is the range of a function?

Back

The range is the set of all possible output values (y-values) for the function.

Front

What does the slope of a line represent?

Back

The slope represents the rate of change of y with respect to x.

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).
