Answer: See below

Step-by-step explanation:

Rewrite in vertex form

f(x) = 2x^2-8x+1

f(x) = 2(x^2-4x) + 1

f(x) + ? = 2(x^2 -4x +?) + 1

To find ?, calculate (b/2)^2, in this case, b is 2

(2/2)^2

= 4

f(x) + 4 = 2(x^2 -4x +4) + 1

f(x) + 2*4 = 2(x^2 -4x +4) + 1

f(x) = 2(x-2)^2 -7

Vertex: (2, -7)

Minimum:  (2 -7) - Same as the vertex
