What is a function?

Back

A function is a relation between a set of inputs and a set of possible outputs where each input is related to exactly one output.

Front

How can you determine if a graph represents a function?

Back

Use the vertical line test: if a vertical line intersects the graph at more than one point, it is not a function.

Front

Solve for n: 6 - (8 - 4n) = 2(2n - 1)

Back

All real solutions.

Front

What is slope-intercept form?

Back

Slope-intercept form is a way of writing the equation of a line as y = mx + b, where m is the slope and b is the y-intercept.

Front

Convert 5x - 3y = -9 to slope-intercept form.

Back

y = (5/3)x + 3.

Front

What does the slope of a line represent?

Back

The slope represents the rate of change of y with respect to x, indicating how steep the line is.

Front

What is the equation of a line parallel to y = 3x - 8?

Back

Any line of the form y = 3x + b, where b is any real number.

Front

Find the equation of the line parallel to y = 3x - 8 that passes through (4, 2).

Back

y = 3x - 10.

Front

What is the value of f(5) if f(x) = 3x - 9?

Back

f(5) = 6.

Front

What is the y-intercept of the line y = 3x - 8?

Back

The y-intercept is -8.
