The inverse, f-1(x), of f(x) =
X + 5
Х
5
can be written as
X- 1

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

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5
