Answer:

A) f(2) = 7/2

B) f'(2) = 5

Step-by-step explanation:

We are given that;

f(x) = (x + 5)/x

f'(x) = 5/(x - 1)

A) Now, f(2) will be gotten by Plugging in 2 for x in to f(x) equation;

f(2) = (2 + 5)/2

f(2) = 7/2

B) similarly, f'(2) will be gotten by Plugging in 2 for x in f'(x) equation. Thus;

f'(2) = 5/(2 - 1)

f'(2) = 5/1

f'(2) = 5
