Answer the following for the given quadratic function.
f(x)=x^2+8x+16
a. what is the vertex (h,k) of f. (h,k)=
The vertex is on the AOS (see part b)
-----------
b. what is the axis of symmetry
AOS is x = -b/2a
-----------------
c. what are the intercepts
Solve the quadratic
--------
d. do a graph to support your answer
e. on what interval is f increasing
f. on what interval is f decreasing
