The axis of symmetry is x=-b/2a for f(x), the axis of symmetry is x=0, because there is no b. when x=0, f(x)=4*0²-1=-1, so the vertex is (0, -1) because a in this case is 4, a positive number, the parabola opens upward, -1 is the lowest value.
for g(x), x=-(-8)/2*1=4, f(x)=4²-8*4+5=-11, the vertex is (4,-11) because a is 1 in this case, a positive number, the parabola opens upward, -11 is the lowest value.
for h(x), x=-(-12)/[2*(-3)]=-2, f(x)=-3*(-2)²-12(-2)+1=13, the vertex is (-2,13) because a is -3 in this case, a negative number, 13 is the largest value.
f(x)'s is obviously larger than g(x) (the graph of f(x) is above that of g(x)), but for h(x), since it opens downward from y=13, it overwraps with part of f(x) and g(x), I'm not sure how you can compare that.
but if we look at the vertex alone, g(x) is the least, then f(x), then h(x) is the largest. I hope all this makes sense.
The answer is actually A g(x) is the lowest amount, h(x) being the middle, and f(x) being the largest, I see where you were going with it, but I think you miscalculated f(x), because it is larger than h(x)
<span>3 is the largest common factor. Therefore, there will be 3 groups with 4 coaches and 14 players. You have to read the question carefully. When I first read the question, I thought I needed to have equal player to coach ratio in each group. I went crazy b/c I have player left over. When I read it several times, I realized I needed to have the same number of coaches per group and the same number of player per group. So the answer to the second part of the questions is 4 coaches and 14 players in each of the 3 groups.</span>
