设函数f(x)在[a,b]上连续,a
设函数f(x)在[a,b]上连续,a

设函数f(x)在[a,b]上连续,a
根据闭区间上连续函数的中间值定理,闭区间上连续函数一定能取到最大值和最小值之间的任何一个值,由于
min(x∈[a,b]){f(x)}

设函数f(x)在[a,b]上连续,a 设函数f(x)在[a,b]上连续,a 设函数f(x)在[a,b]上连续,在(a,b)内可导且f'(x) 设函数f(x)在[a,b]上连续,在(a,b)上可导且f'(x) 设函数f(x),g(x)在区间[a,b]上连续,且f(a) 设函数f 在[a,b]上连续,M=max|f(x)|(a 设函数f(x)在[a,b]上连续,在(a,b)内可导(0 设函数f(x)在闭区间[a,b]上连续,a 设函数f(x)在闭区间[a,b]上连续,a 设函数f(x)在[a,b]上连续,且a 设函数f(x)在[a,b]上连续,且a 设f(x)在[a,b]上连续,且a 设f(x)在[a,b]上连续,且a 设f(x)在[a,b]上连续,且a 设f(x)在[a,b]上连续,a 一条简单的函数连续和极限问题设函数f(x)、g(x)在区间[a,b]上连续,且f(a)>g(a),f(b) 设函数f(x)在[a,b]上连续,在(a,b)可导,且f(a)*f(b)>0,f(a)*f((a+b)/2) 若函数f(x)在[a,b]上连续,a
