I will mark brainliest, kinda urgent

The quadratic function that models the graph on the image is given as follows:
y = (x - 1)² - 1.
The features of the quadratic equation given from the graph are given as follows:
The equation of a quadratic function with vertex (h,k) is defined as follows:
y = a(x - h)² + k.
In which a is the leading coefficient of the function.
From the graph, the coordinates of the vertex are given as follows:
(1,1).
As the vertex is the turning point of the function.
Hence the parameters h and k have values of:
h = 1, k = 1.
Hence:
y = a(x - 1)² + 1.
The y-intercept of the function is of:
y = 2.
This means that when x = 0, y = 2, hence the leading coefficient a is obtained as follows:
2 = a(0 - 1)² + 1
a = 1.
Hence the equation is of:
y = (x - 1)² - 1.
