Math Problem Statement

Identify the zeros, roots, solutions, and x-intercepts of the quadratic function.

Solution

The graph shown is of a quadratic function, typically represented in the form y=ax2+bx+cy = ax^2 + bx + c, and it appears to be a parabola opening upwards. The graph crosses the x-axis at specific points, which are key to identifying the following:

  1. Zeros, Roots, or Solutions: These terms refer to the values of xx where the quadratic function equals zero, meaning the points where the graph intersects the x-axis.

In the graph:

  • The x-intercepts are at x=2x = -2 and x=2x = 2.

Thus, the zeros/roots/solutions of the quadratic function are x=2x = -2 and x=2x = 2.

  1. X-Intercepts: These are simply the points where the function crosses the x-axis. The x-intercepts are the same as the zeros/roots and occur at (2,0)(-2, 0) and (2,0)(2, 0).

Summary:

  • Zeros/Roots/Solutions: x=2x = -2 and x=2x = 2
  • X-Intercepts: (2,0)(-2, 0) and (2,0)(2, 0)

Would you like further details or have any questions?

Here are five related questions to deepen understanding:

  1. How can you derive the quadratic equation from the graph?
  2. What is the vertex form of a quadratic equation, and how would it apply here?
  3. How do the values of aa, bb, and cc in a quadratic equation affect the shape and position of the parabola?
  4. What is the relationship between the discriminant and the number of x-intercepts?
  5. Can a quadratic function have no real x-intercepts? If so, how would that look graphically?

Tip: The vertex of a parabola is a key point, located halfway between the x-intercepts, and can be found using the formula x=b2ax = -\frac{b}{2a} for the standard form of a quadratic equation.
