Math Problem Statement

Using the graph, determine the coordinates of the x-intercepts of the parabola.

Using the graph, determine the coordinates of the x-intercepts of the parabola.

Solution

The graph shows a parabola, and you are asked to find its x-intercepts. X-intercepts are the points where the parabola crosses the x-axis, which happens when y=0y = 0.

From the graph:

  • One x-intercept is at x=6x = -6.
  • The other x-intercept is at x=2x = -2.

Thus, the coordinates of the x-intercepts are: (6,0)and(2,0)(-6, 0) \quad \text{and} \quad (-2, 0)

Would you like more details, or do you have any questions?

Here are five related questions to think about:

  1. How would you find the x-intercepts algebraically if the equation of the parabola was given?
  2. What is the significance of the vertex of a parabola in relation to its x-intercepts?
  3. Can a parabola have no x-intercepts? If so, under what conditions?
  4. How do the values of the coefficients in the quadratic equation affect the x-intercepts?
  5. How can you verify the x-intercepts using the quadratic formula?

Tip: The x-intercepts of a quadratic function are the solutions to the equation ax2+bx+c=0ax^2 + bx + c = 0, which can be solved using factoring, completing the square, or the quadratic formula.
