answer=12:x=1

2)Determine whether f(x)=-5x^2-10x+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^2-3x=28

answer=-4,7

#1, I got x=-1

#2, no

the function opens up, so there is a minimum.

it occurs when x=-1, and that minimum is f(-1), which is 11

#3, ok

#4 graphing f(x) = x^2 + 2x + 2

produces a parabola which lies above the x-axis, so there is no real solution.

#5 ok
