Math Problem Statement

Which answer choice best represents the intercepts of the graph of a quadratic function?

Solution

Looking at the graph, we can determine the x-intercepts and y-intercepts.

  1. X-intercepts: The x-intercepts are the points where the graph crosses the x-axis (i.e., where y=0y = 0). From the graph, the curve crosses the x-axis at x=6x = -6 and x=4x = 4.

  2. Y-intercept: The y-intercept is the point where the graph crosses the y-axis (i.e., where x=0x = 0). From the graph, the curve crosses the y-axis at y=12y = 12.

Now, let's compare this information with the given answer choices:

  • X-intercepts: (-6, 0) and (4, 0)
  • Y-intercept: (0, 12)

From this, the correct answer is Option D:

  • xx-intercept: (6,0)(-6, 0) and (4,0)(4, 0)
  • yy-intercept: (0,12)(0, 12)

Would you like further details or have any questions?

Here are five related questions to expand on this topic:

  1. How can you determine the axis of symmetry for a quadratic function?
  2. What is the formula to find the vertex of a quadratic function in standard form?
  3. How do you calculate the roots of a quadratic equation algebraically?
  4. How does the discriminant of a quadratic equation affect the number of x-intercepts?
  5. Can a quadratic function have more than two x-intercepts?

Tip: The vertex of a quadratic function y=ax2+bx+cy = ax^2 + bx + c is found at x=b2ax = -\frac{b}{2a}, and this x-value gives the axis of symmetry.
