What is a Linear Function?

Back

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

What is a Nonlinear Function?

Back

A nonlinear function is a function that does not graph to a straight line. Examples include quadratic functions, exponential functions, and trigonometric functions.

What does it mean for a relation to be 'Not a Function'?

Back

A relation is 'not a function' if there are two or more ordered pairs with the same first element (x-value) but different second elements (y-values).

What is reflection in geometry?

Back

Reflection is a transformation that flips a figure over a line, creating a mirror image. The line is called the line of reflection.

Front

What is a translation in geometry?

Back

A translation is a transformation that moves every point of a figure the same distance in the same direction.

Front

What does it mean to rotate a figure?

Back

To rotate a figure means to turn it around a fixed point, called the center of rotation, by a certain angle.

Front

What is the x-axis?

Back

The x-axis is the horizontal axis in a coordinate plane, where the y-coordinate is zero.

Front

What is the y-axis?

Back

The y-axis is the vertical axis in a coordinate plane, where the x-coordinate is zero.

Front

How do you write a rule for a translation?

Back

A translation rule is written in the form (x + a, y + b), where 'a' is the horizontal shift and 'b' is the vertical shift.

Front

What is the initial value of a function?

Back

The initial value of a function is the value of the function when the input (x) is zero. It is often represented as the y-intercept in a linear function.
