What is the x-intercept of a graph?

Back

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

Front

How do you find the slope of a line given two points?

Back

The slope (m) is calculated using the formula m = (y2 - y1) / (x2 - x1).

Front

What does the slope of a line represent?

Back

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

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 is the formula for the slope-intercept form of a line?

Back

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

Front

What is exponential growth?

Back

Exponential growth occurs when a quantity increases by a consistent percentage over time.

Front

What is exponential decay?

Back

Exponential decay occurs when a quantity decreases by a consistent percentage over time.

Front

How do you identify a linear function?

Back

A linear function has a constant rate of change and can be represented by a straight line on a graph.

Front

What is the difference between growth and decay in functions?

Back

Growth increases over time, while decay decreases over time.

Front

What does it mean for a function to be undefined?

Back

A function is undefined at points where it does not have a valid output, such as division by zero.
