Hopefully, this works. It all it gave me and maybe try inverting colors if u cant see sry
+129852 OK.....
The vertex is ( 2,1)
The y intercept = (0,5)
So we have this form
y = a ( x - h)^2 + k where (h, k) is the vertex and (x,y) is another point on the parabola
So we have that
5 = a (0 - 2)^2 + 1
5 = a (2)^2 + 1
4 = 4a
1 = a
So we have that
y =1 ( x - 2)^2 + 1
y= x^2 - 4x + 4 + 1
y = x^2 - 4x + 5
Here's the graph, PC : https://www.desmos.com/calculator/gbse0uvdko
