a. f^-1=2x+1/2

b. f^-1=1/2x+1/4

c. f^-1=x-1/2

d. f^-1=1/2x-1/4

2. Find the value of: 8/11{3/8+4/8}6 2/7+12 divide 4

a. 9

b. 7

c. 12 68/77

d. 5

1. d. f^-1=1/2x-1/4

Step-by-step explanation:

1. The inverse of a function is the reflection across the line y=x. The inverse is found algebraically by switching y and x in the equation and solving for y.

f (x) = 2x + 1/2

x = 2y + 1/2

x - 1/2 = 2y

(x - 1/2) / 2 = y

1/2x - 1/4 = y
