Y=X is the equation for the first basic function This is the table for the first basic function
The domain would be (- , )This is because all the values of Y Will give out a real X value
Finding the Domain of a Function Ex.
Y X
-100 -100
0 0
100 100

Y=[X] is the equation of this graphThis is table for the second basic
function.
The domain would be (- , )
Ex. 2
y x
-100 -100
0 0
100 100
This is because all the values of Y Will give out a real X value

Find the Range

This is the graph of the function Y=x^2To find the range you need to lookat the graph to see what values of ythe graph reaches.By looking at the graph, you should see that
the graph reaches all positive values of y and 0, but not the negative values of y.
Because of this, the range for y=x^2 is [0, ), which shows that the graph will start at 0, and reach all positive values of y.
Finding the Range of a Function Ex.

This is the graph of y=x^3By looking at the graph, youshould see that the graph reaches all values of y. (negative, 0, and positive)Because of this, the range ofof y=x^3 is (- , ), which shows that the
graph reaches all values of y.

Bounded above means that there is a FIXED value which the function never rises above.
The Basic Logistic Function is bounded above at 1.
It does not have a single Y value that goes above 1.
Bounded Above

Bounded below means there is a FIXED value which the function never goes below.
The squaring function is bounded below at 0.It never has a Y value that goes below 0.
Bounded Below

A function is said to be bounded when it is bounded above and below.
The sine graph never has a Y value that crosses 1 or -1 thus it is bounded above and below.
Bounded
