Question 230711: For each function,(a) determine whether the graph opens upward or downward,(b) find the axis of symmetry,(c)find the vertex,(d)find the y-intercept, and (e)graph the function.
g(x)=(x-1)to the power of two
I tried putting the equation in standard form which would come out as x to the power of two plus x plus 1. I know what "a" is and "c" but I can't seem to find out "x" because the answer I came out with, which was 1/2, is different form the book which does not give an explanation.

You can put this solution on YOUR website! For each function,
g(x)=(x-1)^2
(a) determine whether the graph opens upward or downward,
Upward
------------------
(b) find the axis of symmetry,
x = 1
--------------------
(c)find the vertex,
(1,f(1)) = (1,0)
---------------------
d)find the y-intercept,
Let x = 0 ; then y = 1
----
(e)graph the function.
===============================================
