Verify Mean value theorem of f(x) = x3 - 3x + 2 for [-1,2].
Verify Mean value theorem of $f(x) = x^3 - 3x + 2$ for [-1,2]. [5]
- Function: $f(x) = x^3 - 3x + 2$ - Interval: $[a, b] = [-1, 2]$, so $a = -1$, $b = 2$ If $f$ is continuous on $[a,b]$ and differentiable on $(a,b)$, then there exists at least one $c \in (a,b)$ such that: $$f'(c) = \frac{f(b) - f(a)}{b - a}$$ $f(x) = x^3 - 3x + 2$ is a polynomial. - Polynomials ...
