Use the inverse of the function y = x2 − 18x to find the unknown values.

Lerok [7]

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.
