Use the domain and range of each of the following relations to determine which is a function.
a. {3, 7, -7,9}
b. {(3,9), (7, - 4), (-7,7)}
c. {(3,9), (7. - 4), (3, 7)}
d. {{3, 9), (1, - 4), (7,6), (-7, 7)}
Please select the best answer from the choices provided

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
