ok, so i'm having a rough time trying to get an answer, mostly because i don't have confidence on my answers. (i already answered question #1)

2) m^2 = 9m-1for this, i rearranged it to become m^2-9m+1=0 (in accordance w/the standard form i think). so my vertex is (4.5, 61.75) and the x-intercepts i got were {0.1125, 8.8875}. my graph is a parabola pointing downward...

3) -25=x^2+10xfor this, i rearranged to get y=x^2+10x+25. i got a vertex of (-5,0). i'm stuck here because i'm not even sure what i did in #2 was correct.

* edit * i tried to get x-intercepts and i got two -5s. i really don't think my x-intercepts are right.

thanks in advance.
