2852=1.2*X*(1+(X-1000)/2000)^1.6
2852=1.2*X*(1+(X-1000)/2000)^1.6

2852=1.2*X*(1+(X-1000)/2000)^1.6
答：
1.2x[1+(x-1000)/2000]^1.6=2852
转化为：
[1+(x-1000)/2000]^1.6=2852/(1.2x)
函数f(x)=[1+(x-1000)/2000]^1.6=(1/2+x/2000)^1.6=(0.5+t)^1.6
函数g(x)=2852/(1.2x)=(2852/2400)/(x/2000)=(2852/2400)/t的图像见下图：
t=0.79=x/2000
x=1580
