Common Assessment 2 Review

Front

What is the formula for a linear function?

Back

A linear function can be expressed in the form f(x) = mx + b, where m is the slope and b is the y-intercept.

Front

How do you evaluate a function at a specific point?

Back

To evaluate a function f(x) at a specific point x = a, substitute a into the function: f(a).

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

How do you determine the slope of a line from its equation?

Back

In the slope-intercept form y = mx + b, m represents the slope of the line.

Front

What does the rate of change represent in a graph?

Back

The rate of change represents how much the output value (y) changes for a unit change in the input value (x).

Front

How can you identify the equation of a vertical line?

Back

The equation of a vertical line is in the form x = a, where a is the x-coordinate of any point on the line.

Front

What is an inequality in the context of functions?

Back

An inequality is a mathematical statement that compares two expressions, indicating that one is greater than, less than, or equal to the other.

Front

How do you find the y-intercept of a linear function?

Back

The y-intercept of a linear function is found by setting x = 0 in the function's equation and solving for y.

Front

What is the significance of the x-intercept in a graph?

Back

The x-intercept is the point where the graph crosses the x-axis, indicating where the output value (y) is zero.
