Test Review Functions and Linear Equations

Front

What is the equation that represents the relationship between the number of months (x) and the total fitness club membership (y) if the club starts with 80 members and increases by 15 members each month?

Back

y = 15x + 80

Front

What is a function?

Back

A relation where every input matches with exactly one output.

Front

Does the table represent a function if each input has a unique output?

Back

Yes, it represents a function.

Front

Does the table represent a function if an input has multiple outputs?

Back

No, it does not represent a function.

Front

What is the definition of a linear equation?

Back

An equation that makes a straight line when graphed.

Front

What is the slope-intercept form of a linear equation?

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

If a fitness club has 80 members and gains 15 members each month, what is the slope of the linear equation?

Back

The slope is 15.

Front

What does the y-intercept represent in the context of the fitness club membership?

Back

The initial number of members when x = 0, which is 80.

Front

What is the difference between a function and a relation?

Back

A function is a specific type of relation where each input has exactly one output.

Front

How can you determine if a set of ordered pairs is a function?

Back

Check if any input value is repeated with different output values.
