Core 3 Unit 2 Flashcards
How to find gf(x)
Find f(x) and then insert that as the x value for g(x)
What is another notation for f(x)
f -> x
What is the range
The values that the y values can take
What is the domain
The value that the x values can take
What is one-to-one function?
It is when each x value only maps to one distinct y value
What is a many-to-one function?
Each y value can be obtained by two different x values.
Which mapping is not a function?
One-to-many mappings.
What is a one-to-many mapping?
A mapping where one x value creates two y values
What is an even function?
Where f(-x) = f(x)
What is an odd function
Where f(-x) = -f(x)
What is a periodic function?
A function that keep repeating itself in a set interval (period.) It is measured in degrees.
How do the graphs of inverse functions relate for one-to-one functions?
They are reflections in the line y=x
How to find the domain and range of an inverse function?
The new domain is the original range, and the new range is the original domain.
