What is function notation?

Back

Function notation is a way to represent a function using symbols, typically written as f(x), where 'f' is the name of the function and 'x' is the input variable.

How do you evaluate a function at a specific point?

Back

To evaluate a function at a specific point, substitute the value of the input variable into the function's equation and simplify.

What defines a function?

Back

A function is defined as a relation where each input (x-value) has exactly one output (y-value).

Front

What is a relation that is not a function?

Back

A relation is not a function if at least one input (x-value) is associated with more than one output (y-value).

Given f(x) = -4x - 10, how do you find x when f(x) = 10?

Back

Set -4x - 10 equal to 10, then solve for x: -4x - 10 = 10 leads to x = -5.

What does it mean for a table to represent a function?

Back

A table represents a function if each x-value corresponds to only one y-value.

Front

What is the significance of the x-value in a function?

Back

The x-value is the input of the function, and it determines the corresponding y-value (output) based on the function's rule.

How can you tell if a mapping is a function?

Back

A mapping is a function if every input (x-value) is paired with exactly one output (y-value).
