Question
Rachel is looking at a function where she needs to identify the cost (y-value) to be 0. Which of the following should Rachel choose as the x-value where this happens? X=-6 X=2 X=-2 and x2 This doesn’t occur as there are no x intercepts
**Question:** Rachel is looking at a function where she needs to identify the cost (y-value) to be 0. Which of the following x-values should she choose where this happens? **Graph Explanation:** The graph shown is a parabola opening upwards, intersecting the y-axis at the origin (0,0). The x-axis is labeled with values ranging from -5 to 5, and the y-axis is labeled from -3 to 10. The parabola appears to be symmetric around the y-axis, indicating that it is centered at the origin. **X-Intercepts:** The parabola crosses the x-axis at the points (-3, 0) and (3, 0), indicating that these are the x-values where the y-value, or cost, is 0. Rachel should choose either x = -3 or x = 3 where the y-value is 0.
