consider the following table
x -2,
-1,
0

2
y
7
4

7
does the table represent a function
A. The table represents a function because each element in the range is associated with exactly one element in the domain.
B. The table does not represent a function because each element in the domain is associated with exactly one element in the range.
C. The table represents a function because each input has exactly one output.
D. The table does not represent a function because each output does not have exactly one input.

To find the equation that represents the relationship between the number of words typed and the number of minutes, we can observe the pattern in the data. The number of words typed increases by 70 after each additional minute.
So, the equation for the relationship would be:
y = 70x
To find out how many words Mrs. Garcia will type in 49 minutes, we can simply substitute x = 49 into the equation:
y = 70 * 49
y = 3430
Therefore, Mrs. Garcia will type 3430 words in 49 minutes.
So, the equation for the relationship would be:
y = 70x
To find out how many words Mrs. Garcia will type in 49 minutes, we can simply substitute x = 49 into the equation:
y = 70 * 49
y = 3430
Therefore, Mrs. Garcia will type 3430 words in 49 minutes.

To find the domain value that corresponds to an output of f(x) = 11, we need to set up the equation as follows:
4x - 5 = 11
Add 5 to both sides:
4x = 16
Divide by 4:
x = 4
Therefore, the correct answer is:
B. 4
4x - 5 = 11
Add 5 to both sides:
4x = 16
Divide by 4:
x = 4
Therefore, the correct answer is:
B. 4
