Question 1104342: 8. Let f(x)=x^2 - 4x + 5.
a. Find the equation of the axis of symmetry of the graph of f.
b. The function can also be expressed in the form f(x) = (x- h)^2 + k.
(i) Write down the value of h.
(ii) Find the value of k.

Add and subtract to the right hand side and put into the form in which you can directly read the vertex AND the symmetry axis.

Vertex is (2,1) and axis of symmetry is x=2.
