Which of the following ordered pairs belongs to the graph of f(x)
Lera25 [3.4K]

Answer:

The second choice, (-1,\, 12).

Step-by-step explanation:

Note, that the expression y = f(x) is an equation. A point (x,\, y) is on the graph of y = f(x)\! if and only if the value of x and y satisfy this equation; that is: in other words, the y\!-coordinate of that point (the second number in the tuple) should be equal to f(x), which is equal to (-3\, x +9) (evaluated where x\! is equal to the first number in the tuple.

For each tuple in the choices, calculate the value of f(x) where x is equal to the first number of each tuple. Compare the result to the second number in that tuple. That choice corresponds to a valid point on y = f(x) only if these two numbers match.

  • First choice: x = 1, f(x) = f(1) = -3 + 9 = 6. That's not the same as the second number, -10. Therefore, this point isn't on the graph of y = f(x).
  • Second choice: x = -1, f(x) = f(-1) = (-3)\times (-1) + 9 = 3 + 9 = 12. That matches the second number in the tuple. Therefore, this point is on the graph of y = f(x).
  • Third choice: x = 2, f(x) = f(2) = (-3)\times 2 + 9 = 3. That's not the same as the second number, (-3). Therefore, this point isn't on the graph of y = f(x).
  • Fourth choice: x = -2, f(x) = f(-2) = (-3)\times (-2) + 9 = 15. That's not the same as the second number, 13. Therefore, this point isn't on the graph of y = f(x).
