Algebra 1 Chapter 3 Review

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

What does the graph of y = -x + 2 look like?

Back

The graph is a straight line with a slope of -1 and a y-intercept of 2.

Front

What is a constant rate of change?

Back

A constant rate of change means that for every unit increase in x, there is a consistent increase in y.

Front

How do you determine if a function is linear?

Back

A function is linear if it can be represented by a straight line on a graph.

Front

What is the average rate of change?

Back

The average rate of change is calculated by the formula (change in y) / (change in x).

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the rise over run.

Front

What is a y-intercept?

Back

The y-intercept is the point where the graph of a function crosses the y-axis.

Front

What does it mean for a function to be nonlinear?

Back

A nonlinear function does not create a straight line when graphed; it may curve or have varying slopes.

Front

How do you find the slope from two points?

Back

Use the formula: slope = (y2 - y1) / (x2 - x1).

Front

What is a function?

Back

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