Question
The graph of a certain parabola in the xy-plane intersects the y-axis once and the x-axis twice. Which of the following forms of the parabola's equation gives they-value of they-intercept as a constant?
- y = (2x - 3)(5x + 7)
- y = 10x2 – x - 21
The correct answer is: y = 10x2 – x - 21
In choice ‘’C’’ y intercept = ‘’- 21 ‘’ which is constant in that equation, and it has ‘’2’’ solutions.
