This will be a multiple post thing so please bear with me. If my answers are wrong then please explain I'll post my work as needed thanks.
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
