The given equation is
First we solve for y, and for that, we have to islolate y, that is
And it pass the vertical line test. So here y is a function of x .
So we can define the given equation as y as a function of x .

Answer: Vertex (5 ,-9)
Step-by-step explanation:
Given : Function f(x) = (x – 8)(x – 2).
To find : What is the vertex of the quadratic function .
Solution : We have given that f(x) = (x – 8)(x – 2).
On removing parenthesis
f(x) = x²-2x -8x +16.
f(x) = x²-10x +16.
We need to find vertex of this function ,
Vertex: (h, k)
h = -.
Plugging values
h = -.
h = 5 this is the x- coordinate,
Now , we will plug x= 5 in quadratic function .
k = (5)²-10(5)+16.
k = 25-50 + 16
k= -9.
Vertex (5 ,-9)
Therefore, Vertex (5 ,-9).
The slope of the graph of the function is equal to 0 for x between x = -3 and x = -2.
The slope of the graph of the function is equal to 0 for x between x = 3 and x = 4.
The greatest value of y is y = 4.
The smallest value of y is y = -3.
