The graph of the quadratic function f(x) = -4(x - 8)² + 4 opens downward and has maximum value at (8,4)
Describing the graph of the quadratic function
From the question, we have the following parameters that can be used in our computation:
f(x) = -4(x - 8)² + 4
A quadratic function is represented as
f(x) = a(x - h)² + k
Where
Leading coefficient = a
Vertex = (h, k)
By comparison, we have
Leading coefficient = -4
Vertex = (8, 4)
The leading coefficient is negative
This means that the function has a maximum at (8, 4) and it opens downward
