1)Identify the yintercept and the axis of symemetry for the graph of f(x)=3x^2+6x+12.
answer=12:x=1
2)Determine whether f(x)=5x^210x+6 has a maximum or minimum value and find that value.
answer=maximum 1
3)Solve x^2=4x by graphing and indicate the roots.
answer=0,4
4)Solve x^2+2x=2 by graphing and indicate the roots.
answer=1,1
5)Solve by factoring:x^23x=28
answer=4,7
