What is the result of (5x^4 - 4x^3 - 2x^2 + x - 19) - (x^4 + 5x^3 + 8x^2 + x + 5)?

Back

4x^4 - 9x^3 - 10x^2 - 24

Front

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

Back

Slope (m) = (y2 - y1) / (x2 - x1)

Front

What is the range of a relation?

Back

The range is the set of all output values (y-values) of a function or relation.

Front

Convert the equation x + 6y = -2 to slope-intercept form.

Back

y = -1/6x - 1/3

Front

What is the slope of the line represented by the equation y = 1/2x + 3?

Back

The slope is 1/2.

Front

What does it mean for a function to be linear?

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 standard form of a linear equation?

Back

Ax + By = C, where A, B, and C are constants.

Front

How do you determine if a relation is a function?

Back

A relation is a function if each input (x-value) has exactly one output (y-value).

Front

What is the difference between the domain and range of a function?

Back

The domain is the set of all possible input values (x-values), while the range is the set of all possible output values (y-values).

Front

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

Back

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