Note that when x=0, y=-6, so d cannot be right. Note that 2 and -1.5 are solutions. The only answer choice that has both as zeroes is a.
If D is the midpoint of GH, then GH equals 2(DH) = 16
16 = 4x - 1
4x = 17
x = 17/4
x = 4.25
Q 1. 1,776 and 1,396
q 2. 1,250
q 3. 3.5 million
It is a polynomial, and the degree is quartic
hope this helps
