Hey, I can't remember all the questions but here are some of my answers. Let me know if you disagree with any!
1) m=-5/3 B(-3,4)k=-30
2) (3rt5)^2=45 75-32rt5
Can't remember the rest so here are some of my other answers I remembered in random order:
Area under curve=81/4 Area shaded region=45/4
(x-7/4)-41/4 (asked for rational form so use fractions) minimum point=-41/4 graph translated by vector [1/2, 41/4]
d^2y/dx^2=-2x-9x^2 sub in x-coord of p to get 45, 45>0 therefore minimum
B(12,-7) m=-4/7 m(tangent)=7/4 7x-4y+18=0
tangent for k (used b^2-4ac=0) k=20 k=4
(x-5)^2+(y+3)^2=65 length of CT=9
y=-32x-40 x-coord Q=-5/4
For graph I had n-shaped parabola intersect y-axis at 8 and x-axis at -1+-rt5
Three linear factors were (x-3)(x-4)^2
For the remainder theorem I think I got 20
