a) find the y-int., the equation of the axis of symmetry, and the x-coordinate of the vertex
b)make a table of values that includes the vertex
c)use this information to graph the function
18) f(x)=x^2+2x+1:
:

:
vertex is at (,)
:
line of symmetry is
:
to find y intercept set x to zero....
so y intercept is 1: (0,1)
:
now just find a few more values of y for chosen x values
:
such as when x=-1--->y=(-1)^2+2(-1)+1=0
:
do this for as many points as you like to get a picture of the graph
:
here is the graph
:
