- In quadrant 3, the curve rises to its maximum at point (0 comma negative 3).
- In quadrant 4, the curve then falls.
The graph of the polynomial function , where , is shown. The y-intercept of the graph is . What is the value of ?
Correct answer: -3
Explanation
The correct answer is . The y-intercept of the graph of a function in the xy-plane is the point where the graph crosses the y-axis. The graph of the polynomial function shown crosses the y-axis at the point . It's given that the y-intercept of the graph is . Thus, the value of is .
