A semipro baseball league has teams with 21 players each. League rules state that a player must be paid at least $15,000,and that the total of all players’ salaries for each team cannot exceed $700,000. What is the maximum possible salary,in dollars,for a single player?
A. 270,000 B. 385,000 C. 400,000 D. 430,000 E.700,000
当0<a<1时,下列不等式成立的是
A. a<a B. log0.1> log0.2
C. a<a D. log2< log3
函数f(x)=log(x-2)+3,a>0,a1的图像过点(4,),则a的值为
A. B. C. 4 D.
已知a=log0.3,b=2,c=0.3,则a,b,c三者的大小关系是
A. a>b>c B. b>a>c C. b>c>a D. c>b>a
设函数f(x)=a(a>0),且f(2)=4,则
A. f(-1)>f(-2) B. f(1)>f(2)
C. f(2)<f(-2) D.f(-3)>f(-2)
已知函数f(x)=x+1,xR,则下列各式成立的是
A. f(x)+f(-x)=2 B. f(x)f(-x)=2
C. f(x)=f(-x) D. –f(x)=f(-x)
