**West Virginia College and Career Readiness Education Standards**. A function is a rule that is performed on a number, called an input, to produce a result called an output. The rule consists of one or more mathematical operations that are performed on the input. An example of a function is y = 2x + 3, where x is the input and y is the output. The operations of multiplication and addition are performed on the input, x, to produce the output, y. By substituting a number for x, an output can be determined. Read More...

Functions

WV.M.8.F. Functions

Define, evaluate, and compare functions.

M.8.11. Understand that a function is a rule that assigns to each input exactly one output. The graph of a function is the set of ordered pairs consisting of an input and the corresponding output.

WV.M.1HS8. 8th Grade High School Mathematics I

Linear and Exponential Relationships

Define, evaluate, and compare functions.

M.1HS8.12. Understand that a function is a rule that assigns to each input exactly one output. The graph of a function is the set of ordered pairs consisting of an input and the corresponding output.

Understand the concept of a function and use function notation.

M.1HS8.15. Understand that a function from one set (called the domain) to another set (called the range) assigns to each element of the domain exactly one element of the range. If f is a function and x is an element of its domain, then f(x) denotes the output of f corresponding to the input x. The graph of f is the graph of the equation y = f(x).

Construct and compare linear, quadratic, and exponential models and solve problems.

M.1HS8.28. Distinguish between situations that can be modeled with linear functions and with exponential functions.

M.1HS8.28.a. Prove that linear functions grow by equal differences over equal intervals; exponential functions grow by equal factors over equal intervals.

WV.M.A18. High School Algebra I for 8th Grade

Linear and Exponential Relationships

Define, evaluate and compare functions.

M.A18.19. Understand that a function is a rule that assigns to each input exactly one output. The graph of a function is the set of ordered pairs consisting of an input and the corresponding output.

Understand the concept of a function and use function notation.

M.A18.22. Understand that a function from one set (called the domain) to another set (called the range) assigns to each element of the domain exactly one element of the range. If f is a function and x is an element of its domain, then f(x) denotes the output of f corresponding to the input x. The graph of f is the graph of the equation y = f(x).

Construct and compare linear, quadratic, and exponential models and solve problems.

M.A18.35. Distinguish between situations that can be modeled with linear functions and with exponential functions.
