Step 1
Let the general formula for the quadratic function is
y=a(xh)2+k
Here (h, k) is the vertex of the quadratic function.
From the table, the two values of x give the same value of y so the vertex point lies in between them.
So, the vertex is (1, 1)
The general form of the quadratic function is,
y=a(x1)2+1
To find the value of a, use the point (0, 0)
0=a(01)2+1
0=a+1
a=1
Therefore, the general form of the quadratic function is y=1(x1)2+1
