- 硫化氢气体的爆炸极限是() A: 4.0% B: 44% C: 5% D: 5% E: 8% F: 44%
- 下面代码的执行结果为( )。def f(values): values[0] = 44v = [1, 2, 3]f(v)print(v) A: [1, 44] B: [1, 2, 3, 44] C: [44, 2, 3] D: [1, 2, 3]
- 一次函数y=f(x)满足条件f(2)=1,f(3)=4,则f(4)=______。 A: 4 B: 5 C: 6 D: 7
- f(x)=x2+bx+c,x∈R,有f(2+x)=f(2-x),则( ) A: f(1)<f(2)<f(4) B: f(2)<f(4)<f(1) C: f(4)<f(2)<f(1) D: f(2)<f(1)<f(4) E: f(1)<f(4)<f(2)
