Practice Question
The graph of the equation y = x^2 + 4x - 5 is shown on the grid. Which statement is true when y = 0?
Answer Choices
- A: x= -5 and x=1
- B: x= -2
- C: x= -5 and x = 0
- D: x= -9
Correct Answer: A
Rationale: Solve x^2 + 4x - 5 = 0. Factor: (x+5)(x-1) = 0, so x = -5 or x = 1. Thus, the correct answer is x= -5 and x=1.
