Question

a parabola on a grahp opens upward, and its vertex is -3,-10, so what is correct about this graph? Is th a-value negative? nope. Is the vertex at 3,-10? nope. but what about these two?
The c-value of the equation in standard form is −10



.
The c -value of the equation in standard form is negative 10 .

The c-value of the equation in standard form is −1

okay, so i did notice that as the line curves upward towards the right it intersects at -1.

Let's clarify a few points about the parabola given your description:

1. **Vertex**: You mentioned the vertex of the parabola is at the point (-3, -10). This means the parabola opens upward and its lowest point (the vertex) is at (-3, -10).

2. **C-value**: In the standard form of a parabola represented by the equation \(y = ax^2 + bx + c\), the **c-value** is the y-intercept of the parabola, which is the value of \(y\) when \(x = 0\). For your parabola, the c-value is not directly given but can be derived based on the equation of the parabola if you have the appropriate parameters.

If the equation of the parabola is in vertex form, \(y = a(x + 3)^2 - 10\), then the c-value would need to be determined by finding the y-value when \(x = 0\).

Plugging in \(x = 0\):
\[
y = a(0 + 3)^2 - 10 = 9a - 10
\]
To identify the correct c-value, you need to know the value of \(a\).

3. **Sign of a**: You mentioned the parabola opens upward, which implies that the **a-value** is positive (not negative), confirming that \(a > 0\).

4. **The statement about c**: If it states that the c-value of the equation in standard form is −10, unless given or calculated, it's not accurate to assert that without having the specific coefficients available. The statement that the c-value of the equation in standard form is −1 needs further clarification. It could be true if depending on the equation context.

5. **The intersection at -1**: If the graph intersects at \(x = -1\), that is a point on the parabola. However, it does not directly specify the c-value. You can evaluate the equation at \(x = -1\) to see what it yields, but this does not directly give you the c-value.

In conclusion:

- The vertex is correct at (-3, -10).
- The a-value must be positive.
- The c-value could only be specifically determined with more context about the parabola (like its equation).
- If the graph intersects at \(y = -1\) at some point, you can analyze that specific point, but it doesn't define the c-value without additional context.
