Answers: Choice A and Choice C

Explanation:

  • a) Is a function. We don't have any repeated x values. Each input leads to exactly one output.
  • b) Not a function. The input x = -4 leads to multiple outputs.
  • c) Is a function. Similar to choice A, we don't have any repeated x values.
  • d) Not a function. The graph fails the vertical line test. We can draw a vertical line through more than one point.
