ANSWER

b=1, c=81, and d=9.

EXPLANATION

The given function is:

y={x}^{2}-18x

This function is the same as:

y={(x - 9)}^{2}-81

To find the inverse of this function, we interchange x and y.

x={(y-9)}^{2}-81

Solve for y:

x+81={(y- 9)}^{2}

Take square root of both sides:

\pm \sqrt{x + 81}=y-9

y=\pm \sqrt{x + 81}+9

Hence,

b=1, c=81, and d=9.
