Let the function f be continuous and differentiable for all x. Suppose you are given that f(−1)=−3, and that f'(x) for all values of x. Use the Mean Value Theorem to determine the largest possible value of f(5).

Answer:
Step-by-step explanation:
By MVT,
[tex]f'(c) = \frac{f(5)-f(-1)}{5-1}[/tex]
[tex]4f'(c)= f(5) + 3\rightarrow f(5) = 4f'(c) - 3[/tex]
Moreover, [tex]f'(x)\leq 4~~~~~~ \forall x,[/tex]
[tex]f(5) \leq 16 - 3 =13[/tex]
Hence the largest possible value of f(5) is 13
