Math Problem Statement

Which quadratic function is in standard form?

Solution

The problem asks which of the given quadratic functions is in standard form. Standard form of a quadratic equation is:

ax2+bx+cax^2 + bx + c

where aa, bb, and cc are constants.

Now let's analyze each option:

  1. y(x)=(x6)2+16y(x) = -(x - 6)^2 + 16:

    • This is in vertex form, not standard form. The vertex form is a(xh)2+ka(x - h)^2 + k.
  2. f(x)=(x+1)2+0f(x) = (x + 1)^2 + 0:

    • This is also in vertex form.
  3. g(x)=3(x3)2+4g(x) = -3(x - 3)^2 + 4:

    • This is in vertex form as well.
  4. h(x)=2x28x10h(x) = 2x^2 - 8x - 10:

    • This is in standard form because it follows the format ax2+bx+cax^2 + bx + c.

Thus, the correct answer is h(x)=2x28x10h(x) = 2x^2 - 8x - 10.

Would you like further details or have any questions?

Here are 5 questions to consider:

  1. How can we convert vertex form to standard form?
  2. What is the role of the coefficient aa in a quadratic function?
  3. How do the constants bb and cc affect the graph of a quadratic function?
  4. What is the general form of the quadratic equation?
  5. How does completing the square relate to quadratic functions?

Tip: Vertex form is useful for identifying the vertex of a parabola easily, but for solving and analyzing, standard form is often preferred.
