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 value
Monica [59]

Answer:

Step-by-step explanation:

By MVT,

f'(c) = \frac{f(5)-f(-1)}{5-1}

4f'(c)= f(5) + 3\rightarrow f(5) = 4f'(c) - 3

Moreover, f'(x)\leq 4~~~~~~ \forall x,

f(5) \leq 16 - 3 =13

Hence the largest possible value of f(5) is 13

You rent an apartment that costs $1500 per month during the first year, but the rent
belka [17]
<h3>Answer:</h3>

\begin{cases}a_1 = 1500\\a_n = 140+a_{n-1}\end{cases}

==============================

Explanation:

a_1 = 1500 means the first term is 1500, ie this is the first rent value.

To get the next term, we add on $140

So

a_2 = 140+a_1 = 140+1500 = 1640

and

a_3= 140+a_2= 140+1640 = 1780

and so on.

In general, the nth term a_n is found by adding 140 to the term just before it a_{n-1}

So that's where a_n = 140+a_{n-1} comes from.
