What is domain? what is range? how do you get from one to the other?

The domain is the set of all possible x-values which will make the function "work", and will output real y-values.  (Minimun x value to maximum x value)

The range of a function is the spread of possible y-values (minimum y-value to maximum y-value)

Step-by-step explanation:

When trying to find the domain and range from a graph, the domain is found by looking at the graph from left to right.  The range is found by looking at the graph from top to bottom.

there is no grid

step-by-step explanation:

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
