Answer
### The range of the function \( f(x) = -(x-5)^2 + 4 \) is
.
Explanation
## Step 1: Identify the Vertex of the Parabola### The function \( f(x) = -(x-5)^2 + 4 \) is a quadratic function in vertex form, \( f(x) = a(x-h)^2 + k \), where \( (h, k) \) is the vertex. Here,
and
. Therefore, the vertex of the parabola is at the point \( (5, 4) \).## Step 2: Determine the Direction of the Parabola### The coefficient
indicates that the parabola opens downwards. This means the vertex represents the maximum point on the graph.## Step 3: Find the Range of the Function### Since the parabola opens downwards and the maximum value of the function occurs at the vertex, the range of the function is all values less than or equal to the y-coordinate of the vertex. Thus, the range is
.
