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

What is the value of f(0) if f(x) = 2x + 4?

Back

4

Front

How do you determine if a set of values represents a function?

Back

A set of values represents a function if no two ordered pairs have the same first element.

Front

Simplify the expression (x - 3)².

Back

x² - 6x + 9

Front

Evaluate f(x) = -2x + 13 for f(10).

Back

-7

Front

What is the difference between (3 - 2x + 2x²) and (4x - 5 + 3x²)?

Back

-x² - 6x + 8

Front

What is the standard form of a quadratic equation?

Back

The standard form of a quadratic equation is ax² + bx + c = 0, where a, b, and c are constants.

Front

What does it mean for a function to be linear?

Back

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

Front

What is the slope-intercept form of a linear equation?

Back

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

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated as m = (y2 - y1) / (x2 - x1).
