The parabola will have a vertex at left parenthesis 0 comma 0 right parenthesis .

The parabola will have a vertex at (1,0)
.

Answer 1

To analyze the equation \( y = -5(x)^2 + 1 \), let's identify key features of its graph:

1. **Direction of Opening**:
- The coefficient of \( x^2 \) is \(-5\), which is negative. Therefore, the parabola opens **downwards**.

2. **Vertex**:
- The standard form of a parabola is \( y = a(x - h)^2 + k \), where \((h, k)\) is the vertex.
- In this equation, we can see that it can be rewritten to identify the vertex more clearly:
\[
y = -5(x - 0)^2 + 1
\]
- Here, \( h = 0 \) and \( k = 1 \), which gives the vertex at \((0, 1)\).

Given these observations, we can evaluate the provided statements:

1. **The parabola will open downwards.** - **True**
2. **The parabola will have a vertex at \((-1,0)\).** - **False**
3. **The parabola will have a vertex at \((0,0)\).** - **False**
4. **The parabola will have a vertex at \((1,0)\).** - **False**

**Conclusion**: The correct statement is **"The parabola will open downwards."**
