Math Problem Statement
Which of the following graphs would represent the quadratic function ? y=(x+4)squared plus 2
Solution
The equation you're working with is:
This is a quadratic equation in vertex form. The general form of a quadratic equation is , where is the vertex of the parabola.
From the equation , we can deduce that:
- The vertex of the parabola is at .
- Since the coefficient of is positive (it’s 1), the parabola opens upwards.
Now, comparing the two graphs:
- The first graph has a vertex at and opens upwards, which matches the equation given.
- The second graph has a vertex at , which does not match the given equation.
Therefore, the first graph represents the quadratic function .
