Let's analyze the given function:
\[ f(x) = -(x - 1)^2 \]
Characteristics of the Parabola:
-
Vertex: The vertex of the parabola can be found from the equation in vertex form, which is \( f(x) = a(x - h)^2 + k \), where \( (h, k) \) is the vertex. For this equation, we can see that:
- \( h = 1 \)
- \( k = 0 \) Thus, the vertex is: \[ \text{Vertex} = (1, 0) \]
-
Maximum or Minimum Point: The coefficient \( a \) (in front of the squared term) is negative (-1). This indicates that the parabola opens downward. Therefore, the vertex is a maximum point. Thus: \[ \text{Maximum Point} \]
-
Axis of Symmetry: The axis of symmetry for a parabola in vertex form is given by the line \( x = h \). In this case: \[ \text{Axis of Symmetry} = x = 1 \]
-
Domain: The domain of a parabola that opens downwards is all real numbers. Hence: \[ \text{Domain} = (-\infty, \infty) \]
-
Range: Since the vertex is the maximum point at \( y = 0 \) and the parabola opens downward, the range includes all values less than or equal to 0. Thus: \[ \text{Range} = (-\infty, 0] \]
Summary:
- Vertex: \( (1, 0) \)
- Maximum Point: Yes, it is a maximum point.
- Axis of Symmetry: \( x = 1 \)
- Domain: \( (-\infty, \infty) \)
- Range: \( (-\infty, 0] \)
