Turn F(x) into vertex form:
y=x^2+8x+6
y-6=x^2+8x
y-6+16=x^2+8x+16
y+10=(x+4)^2
Thus the vertex is (-4,-10)
This is a minimum because the parabola is up up, or is positive
4/5 mile is 8/10 of a mile. 8/10 divided by 1/10 is 8. she saw eight markers
The critical point is (-30,0) I think
1. 32u is the same as A, B and D but not C
2. True because 32 less than s is the same as s take away 32
