Module 1

Front

If the equation of f(x) goes through (1, 4) and (4, 6), what points does f⁻¹(x) go through?

Back

(4, 1) and (6, 4)

Front

What does it mean to find the inverse of a function?

Back

The x's and y's are switched.

Front

What is the range of the function f(x) if it is defined as [2, ∞)?

Back

The range is [2, ∞).

Front

What is the domain of the function f(x) if it is defined as [-3, ∞)?

Back

The domain is [-3, ∞).

Front

What is the domain of the graph if it is defined as 1 ≤ x ≤ 4?

Back

The domain is 1 ≤ x ≤ 4.

Front

What is the definition of a function?

Back

A relation where each input has exactly one output.

Front

What is the definition of an inverse function?

Back

A function that reverses the effect of the original function.

Front

How do you find the inverse of a function algebraically?

Back

Swap x and y, then solve for y.

Front

What is the vertical line test?

Back

A method to determine if a curve is a function by checking if a vertical line intersects it at most once.

Front

What is the definition of domain in a function?

Back

The set of all possible input values (x-values) for the function.
