F(x) = x + 11
Then use 4 step to find inverse F-1(x)
S1: let F(x) = x + 11
S2: Interchange x <=> y
x = y + 11
S3: Solve for y
11x = y
S4: F(x)-1 = 11x
S1: let y = x + 11
S2: Interchange x <=> y
y + 11 = x
S3: Solve for y
y = x + 11
S4: F(x)-1 = x + 11
S1: let y = x + 11
S2: Interchange x <=> y
x = y + 11
S3: Solve for y
x - 11 = y
S4: F(x) = x
S1: let y = x + 11
S2: Interchange x <=> y
x = y + 11
S3: Solve for y
x - 11 = y
S4: F-1(x) = x - 11

F(x) = 11x
Then use 4 step to find inverse F-1(x)
S1: let F(x), x = 11y
S2: Interchange x <=> y
y = 11x
S3: Solve for y
y = x
S4: F(x)-1 = x
S1: let y = x + 11
S2: Interchange x <=> y
x = 11y
S3: Solve for y
y = 11x
S4: F(x)-1 = 11x
S1: let y = x + 11
S2: Interchange x <=> y
x = 11y
S3: Solve for y
x/11 = y
S4: F(x)-1 = x/11
S1: let y = x + 11
S2: Interchange x <=> y
x = 11y
S3: Solve for y
11/x = y
S4: F(x) = 11/x
