Prove: If f(x) is a continuous function on a closed interval [a, b] and x_{1}, x_{2}, ..., x_{n} are n points in the interval, then there exists c such that:
Prove: If f(x) is a continuous function on a closed interval [a, b] and x_{1}, x_{2}, ..., x_{n} are n points in the interval, then there exists c such that:
Note how to use subscripts, [TEX]f(c)=\frac{f(x_1)+f(x_2)+...+f(x_n)}{n}[/TEX] gives .
