Answer:

Inverse of -6x+22 is

\boxed{-(x-22)/(6)}

Graphs attached

Explanation:

Original function y = k(x) = -6x + 22

To find the inverse of this function

Replace x with y
x = -6y + 22

Solve for x

  • Switch sides
    -6y + 22 = x
  • Subtract 22 from both sides
    -6y + 22 - 22 = x - 22
  • Simplify
    -6y = x - 22
  • Divide by - 6 on both sides

    (-6y)/(-6)=(x-22)/(-6)
  • Simplify

    y=-(x-22)/(6)

    Note: Graphically, the inverse of a function is a reflection of the function about the line y = x
