Write the inverse letter for the matching inverse of each table and graph. Then solve each equation for its inverse.
Write the inverse table letter from below.
Write the inverse graph letter from below.
Write the inverse table letter from below.
Write the inverse graph letter from below.
5.) Algebraically find the inverse of the equation.
f(x) = 2x - 8
6.) Algebraically find the inverse of the equation.
f(x) = 5x - 15

Answer

  1. Inverse table letter: a

  2. Inverse graph letter: c

  3. Inverse table letter: b

  4. Inverse graph letter: d

  5. To find the inverse of f(x) = 2x - 8, swap x and y and solve for y:
    x = 2y - 8
    x + 8 = 2y
    y = (x + 8)/2
    Inverse: f-1(x) = (x + 8)/2

  6. To find the inverse of f(x) = 5x - 15, swap x and y and solve for y:
    x = 5y - 15
    x + 15 = 5y
    y = (x + 15)/5
    Inverse: f-1(x) = (x + 15)/5
