Answer 1

The correct answer is D

Explanation:

Answer 2

`y = (-1)/(2)(x-3)`

Explanation:

To determine the inverse of an equation, simply switch the places of the 'x' and 'y' variables. Therefore:

f(x) = -2x + 3

Use 'y' in place of f(x).

y = -2x + 3

Switch the 'x' and the 'y':

x = -2y + 3

Subtract '3' from both sides:

x - 3 = -2y

Divide both sides by '-2':

`y= (x-3)/(-2)`

Simplify:

`y = (-1)/(2)(x-3)`
