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:
where , , and are constants.
Now let's analyze each option:
-
:
- This is in vertex form, not standard form. The vertex form is .
-
:
- This is also in vertex form.
-
:
- This is in vertex form as well.
-
:
- This is in standard form because it follows the format .
Thus, the correct answer is .
Would you like further details or have any questions?
Here are 5 questions to consider:
- How can we convert vertex form to standard form?
- What is the role of the coefficient in a quadratic function?
- How do the constants and affect the graph of a quadratic function?
- What is the general form of the quadratic equation?
- 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.
