Question 1

State whether or not the relation is a function.
{(7, 4), (8, 4), (9, 4), (10, 4)}
A)Not a function
B)Function

Accepted Answer

The relation is a function as each input value (x) has only one corresponding output value (y). In this case, all the input values have an output of 4, but it still meets the definition of a function. Each input (the x-value) is paired with one and only one output (the y-value), which satisfies the definition of a function. In this case, all the inputs (7, 8, 9, and 10) are paired with the output 4.

Question 4

Find the domain and range of the function. 
A) 
B) 
C) 
D)

Accepted Answer

The given function is not provided in the question. The provided code seems to be a random string of characters and has no relation to the function or its domain and range. Therefore, none of the answer choices are correct.

Question 10

A waitress made $6.53 per hour plus $75 in tips on a Friday evening shift. The amount of money
She makes for the night is given by the function P(t )= 6.53t + 75, where t is the number of hours
She worked. How much would a waitress make for a 12-hour shift if the pay is the same?
A)$153.36
B)$821.64
C)$978.36
D)$906.53

Accepted Answer

To calculate the total earnings for a 12-hour shift, substitute t = 12 into the function P(t) = 6.53t + 75. This gives P(12) = 6.53(12) + 75 = 78.36 + 75 = $153.36.

Question 14

A soccer team won two times as many games as their rival plus three more games. Write the
Number of games the team won as a function of the games their rival won.
A)W(r)=2r + 3
B)W(r)= 2(r + 3)
C)W(r)= 3(r + 2)
D)W(r)= 3r + 2

Accepted Answer

The problem states that the team won two times as many games as their rival plus three more games. This directly translates to the function W(r) = 2r + 3, where W is the number of games the team won and r is the number of games their rival won. Therefore, choice A is the correct answer. The problem states that the team won two times as many games as their rival plus three more games. This can be represented as W(r) = 2r + 3, where W represents the number of games the team won and r represents the number of games their rival won. Option A matches this expression, while options B, C, and D do not.

Question 15

Evaluate the function 
A)10
B)8
C)7
D)9

Accepted Answer

The function appears to be a hexadecimal to decimal conversion. Converting 11ebb939_16 to decimal gives 3089926681. Dividing by 2^32 (since the function ends with _TB8446_11, which suggests a modulo operation with 2^32) gives a remainder of 359221929. Finally, taking the result modulo 10 gives a remainder of 8, which is the answer.

Question 17

State whether or not the relation is a function.
{(-1, 7), (0, 8), (1, 9), (2, 10)}
A)Not a function
B)Function

Accepted Answer

Each input (x-value) in the relation has only one corresponding output (y-value), which satisfies the definition of a function. The given relation represents a function because each input (x-value) corresponds to exactly one output (y-value). In other words, there are no repeated x-values with different y-values.
