inverse of f(x)=cos(x-7)+4

Solution

inverse

f (x) = cos (x - 7) + 4

Solution

arccos (x - 4) + 7

Solution steps

Solve for

cos (x - 7), y = cos (x - 7) + 4

cos (x - 7) = y - 4

cos (a) = b \Rightarrow a = arccos (b)

x - 7 = arccos (y - 4)

Solve for

x, x - 7 = arccos (y - 4)

arccos (y - 4) + 7

Substitute

y = x

arccos (x - 4) + 7
