Answer:

Step-by-step explanation:

1. plug in 4 for F(x) making 4=x:

$f(4)=4(4)+5$

2. multiply 4 and 4:

$f(4)=4(4) +5$ ⇒ $f(4)=16+5$

3. Add 16 and 5 to get your answer:

$f(4)= 16+5$ ⇒ $f(4)=21$

Suppose that 2 ≤ f '(x) ≤ 4 for all values of x. What are the minimum and maximum possible values of

Vesna [10]

Answer:

Step-by-step explanation:

By the Mean Value Theorem, there is at least one number, c, in the interval (1,6) such that

f'(c) = [f(6) - f(1)]/ (6 - 1)

So, f(6) - f(1) = 5f'(c).

Since 2 ≤ f'(c) ≤ 4, 10 ≤ 5f'(c) ≤ 20

So, f(6) - f(1) is between 10 and 20.
