Question

Find the vertex of the graph of the function. f(x) = (x - 10)^2 + 2

Answer 1

Vertex is the point where the graph of the function meets the x function. 
This means that we know one of the coordinates of the vertex X=0 always.
We should calculate f(0) in order to find out point Y.
(0-10)^2=(-10)^2=100
