型号 | 载客量(人/辆) | 租金单价(元/辆)A |
A | 16 | 900 |
B | 22 | 1200 |
(1)请写出y与x的函数关系式(不要求写自变量取值范围);
(2)据资金预算,本次租车总费用不超过11800元,则A型客车至少需租几辆?
(3)在(2)的条件下,要保证全体师生都有座位,问有哪几种租车方案?请选出最省钱的租车方案.

y = sin x, x∈R, y∈[–1,1],周期为2π,函数图像以 x = (π/2) + kπ 为对称轴
y = arcsin x, x∈[–1,1], y∈[–π/2,π/2]
sin x = 0 ←→ arcsin x = 0
sin x = 1/2 ←→ arcsin x = π/6
sin x = √2/2 ←→ arcsin x = π/4
sin x = 1 ←→ arcsin x = π/2
