REVIEW: Unit 3 Part 2

Front

What is the domain of a function?

Back

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

Front

What is the range of a function?

Back

The range of a function is the set of all possible output values (y-values) that the function can produce.

Front

If a swimming pool costs $150 per hour, what is the cost to rent it for 3 hours?

Back

The cost to rent the pool for 3 hours is $450 (3 hours * $150/hour).

Front

If a swimming pool costs $150 per hour, what is the cost to rent it for 4 hours?

Back

The cost to rent the pool for 4 hours is $600 (4 hours * $150/hour).

Front

What is the domain and range for the function representing the cost of renting a pool for 3 or 4 hours?

Back

Domain: {3, 4}, Range: {450, 600}.

Front

What does it mean for a function to have a zero?

Back

A zero of a function is a value of x for which the function's output (y) is zero.

Front

What is a y-intercept?

Back

The y-intercept is the point where a graph intersects the y-axis, representing the output value when the input value (x) is zero.

Front

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

Back

Front

How do you determine the slope from two points on a line?

Back

Front

What is the significance of the slope in a linear function?

Back

The slope indicates the rate of change of the function; a positive slope means the function is increasing, while a negative slope means it is decreasing.
