Question

Which of the following ordered pairs is a solution of the function ƒ(x) = 3x – 1?Question 12 options:A) (–1, 2)B) (–1, –3)C) (–1, –4)D) (–1, 4)

Answer 1

Answer: Option C) (-1,-4)

Explanation:

For this question we compute f(-1):

$\begin{gathered} f(-1)=3(-1)-1. \\ f(-1)=-3-1. \\ f(-1)=-4. \end{gathered}$

Therefore the ordered pair (-1,-4) is a solution to the function f(x)=3x-1.
