Factorable? Discriminant, . Not really factorable.

Complete the Square to put into standard form.

-----
------vertex is at (1,-2).

Symmetry Axis: at x=1.

Intercepts?

-
You can also look for a y-intercept, by letting x=0 and evaluate y. Find f(0).

ANSWER SUMMARY
Vertex (1,-2)
Axis Of Symmetry x=1
Roots
