Practice Question
The equation and the graph represent two linear functions.
Function P: f(x) = 4 - 6x
Function Q:
Which statement compares the y-intercepts of function P and function Q?
Function P: f(x) = 4 - 6x
Function Q:
Which statement compares the y-intercepts of function P and function Q?
Answer Choices
- A: The y-intercept of function P is -6 which is less than the y-intercept of function Q.
- B: The y-intercept of function P is 4 which is equal to the y-intercept of function Q.
- C: The y-intercept of function P is -6 which is greater than the y-intercept of function Q.
- D: The y-intercept of function P is 4 which is greater than the y-intercept of function Q.
Correct Answer: D
Rationale: For P: f(x) = 4 - 6x, y-intercept (x=0) is 4. Without Q's equation, assume its graph shows a y-intercept less than 4 (e.g., 0, common in GED). Thus, the correct answer is The y-intercept of function P is 4 which is greater than the y-intercept of function Q.
