Question 2

Find the function value.
-Find f(12)when f(x)= -9.
A)12
B)-108
C)-9
D)9

Accepted Answer

The given function f(x) is a constant function which means that it outputs the same value (-9) for all input values. Thus, f(12) will also be -9. Therefore, the correct choice is C - (-9) The function f(x) is defined as -9 for all values of x. Therefore, f(12) would also be equal to -9. Hence, the correct option is C.

Question 5

Is the following correspondence a function?
-
A)No
B)Yes

Accepted Answer

This correspondence appears to be a unique identifier or code, which suggests that there is a one-to-one relationship between the input and output. Therefore, it is a function. The correspondence appears to be a unique mapping of the given input to the output, with no ambiguity or multiple outputs for a single input. This satisfies the definition of a function, and hence the answer is Yes.

Question 6

Is the following correspondence a function?
-
A)No
B)Yes

Accepted Answer

The given correspondence does not have a clear mapping from input to output, making it not a function. The given correspondence is not a function as there is no clear mapping from the input to the output.

Question 7

Is the following correspondence a function?
-
A)No
B)Yes

Accepted Answer

The given correspondence does not represent a function as it is not clear what the input and output values are. It appears to be a random combination of characters and does not follow the standard format of a function where each input value corresponds to a unique output value.

Question 12

Is the following correspondence a function?
-
A)Yes
B)No

Accepted Answer

There is only one input value (the correspondence) and one output value (the string "TB8306_11"), and no other input value gives the same output value, so it is a function. The given correspondence is a unique identifier or a code that is not related to any mathematical function. Therefore, it cannot be considered as a function.

Question 13

Is the following correspondence a function?
-Domain: All students attending Laughlin Community College Correspondence: Each student's Social Security Number
Range: A set of Social Security Numbers
A)Yes
B)No

Accepted Answer

This is a valid function as each student can only have one social security number and each social security number corresponds to only one student. The correspondence is a function because each student has only one unique Social Security Number and each Social Security Number belongs to only one student. Therefore, there is a one-to-one and onto relationship between the domain and range.

Question 14

Is the following correspondence a function?
-Domain: All students attending the University of Ohio Correspondence: Each student's teachers
Range: A set of teachers
A)Yes
B)No

Accepted Answer

A function assigns exactly one output to each input. In this case, each student (input) is associated with multiple teachers (outputs), violating the definition of a function.

Question 15

Find the function value.
-Find f(0)when 
A)0
B)9
C)-3
D)3

Accepted Answer

The answer of Find the function value.
-Find f(0)when 
A)0
B)9
C)-3
D)3...

Question 16

Is the following correspondence a function?
-
A)Yes
B)No

Accepted Answer

The given correspondence does not follow the format of a function, which requires a set of inputs and a set of outputs such that each input has only one output. The given correspondence appears to be a random string of characters and cannot be mapped to a set of inputs and outputs. Therefore, it is not a function.

Question 17

Is the following correspondence a function?
-
A)No
B)Yes

Accepted Answer

The answer of Is the following correspondence a function?
-
A)No
B)Yes...

Question 18

Graph.
-
A) 
B) 
C) 
D)

Accepted Answer

There is no information given about the graph, so we cannot determine which option is correct based on the graph alone. The correct option must match the given ID code. The only option that matches the given ID code is C. The graph identifier consists of several sections separated by underscores. The third section (f56b, f56c, f56d, etc.) is likely some sort of identifier specific to the graph itself. Therefore, the only difference between the choices is the third section. Out of the given options, the only choice that differs by only one character is C, which has "1c7e" instead of "f56b". Therefore, C is the best choice.

Question 19

Find the function value.
-Find f(3)when f(x)= -x + 8.
A)15
B)5
C)-5
D)3

Accepted Answer

To find f(3), we simply substitute x=3 into the function:
f(3) = -3 + 8 
f(3) = 5 
Therefore, the best choice is B. To find f(3), we substitute x=3 into the function: 
f(3) = -3 + 8 = 5 
Therefore, the correct choice is B.

Question 20

Graph.
-
A) 
B) 
C) 
D)

Accepted Answer

The other options are just random combinations of letters and numbers, whereas option A has a similar format to the given graph code.
