What does it mean to transform a function?

Back

Transforming a function involves changing its position or shape on the graph. Common transformations include translations (shifting left, right, up, or down), reflections (flipping over an axis), and stretches or compressions (changing the size).

How do you represent a system of equations for a word problem?

Back

A system of equations can be represented by defining variables for the unknowns, then creating equations based on the relationships described in the problem. For example, if p is pennies and n is nickels, the equations could represent the total number of coins and their total value.

What does it mean for a function to be increasing or decreasing?

Back

A function is increasing on an interval if, as the input values increase, the output values also increase. Conversely, a function is decreasing on an interval if, as the input values increase, the output values decrease.

How do you find the intersection of two lines?

Back

To find the intersection of two lines represented by equations, solve the system of equations simultaneously. This can be done using substitution or elimination methods to find the values of the variables that satisfy both equations.

What is the purpose of using a system of equations?

Back

A system of equations is used to find the values of multiple variables that satisfy all equations in the system simultaneously. This is useful in real-world problems where multiple conditions must be met.
