Which quadratic inequality does the graph below represent?

Which quadratic inequality does the graph below represent?

Solution

The graph you uploaded shows a parabola that opens upwards, which implies that the quadratic term has a positive coefficient for x2x^2. Additionally, the shading is below the curve, indicating that the inequality involves \leq or <<.

Let's analyze the form of the quadratic equation:

  1. The parabola opens upwards, so the coefficient of x2x^2 must be positive.
  2. The vertex of the parabola is at (2,5)(2, -5), so the equation should have a vertex form related to that.
  3. Since the shading is below the curve, the inequality must be yquadratic expressiony \leq \text{quadratic expression}.

The general form is y2x28x+3y \leq 2x^2 - 8x + 3.

Thus, the correct inequality is: y2x28x+3y \leq 2x^2 - 8x + 3

Answer:

The first option: y2x28x+3y \leq 2x^2 - 8x + 3.

Do you need any further details or explanations? Here are five related questions that might expand on this concept:

  1. How do you find the vertex of a quadratic equation in standard form?
  2. Why does a positive x2x^2 term make the parabola open upwards?
  3. How does the inequality symbol affect the graph of a quadratic inequality?
  4. Can you convert a quadratic equation to vertex form?
  5. How do you determine whether to use \leq or \geq for a quadratic inequality?

Tip: When graphing quadratic inequalities, always observe the shading (above or below the curve) to determine whether it involves \geq or \leq.
