Describe the axis of symmetry of the graph of the quadratic function represented by the equation y =ax2+bx+c when b =0.

answer:

at time x=0 we have 1000, at time x=1 we have 2000, at time x=2 we have 4000.  

so that's an initial value of 1000 and a ratio of 2,

y = 1000 (2^x)

hope this !

the correct answer is the last option

if it's asking for the proper expression then it could be 8x= .8 each person would get a .1   portion of the turkey
