Answer:

  • A. {7, 1, -8}

Step-by-step explanation:

Given function:

  • f(x) = -3x + 1

Set of domain is:

  • {-2, 0, 3}

To find each term of the range substitute the terms of the domain in the function:

  • f(-2) = -3(-2) + 1 = 6 + 1 = 7
  • f(0) = -3(0) + 1 = 0 + 1 = 1
  • f(3) = -3(3) + 1 = -9 + 1 = - 8

Set of range:

  • {7, 1, -8}

Correct option is A
