Use the inverse of the function y = x2 - 18x to find the unknown values. y = + / = square root of bx+c+d

Y = x2 - 18x

We look for the inverse of the function.

To do this, let's determine the value of x:

y = x2 - 18x

y = (x + (-18/2)) ^ 2 - ((-18) ^ 2/4) + 0

y = (x - 9) ^ 2 - 81

y + 81 = (x - 9) ^ 2

+ / - root (y + 81) = (x - 9)

+ / - root (y + 81) + 9 = x

We return the change:

f (x) ^ - 1 = + / - root (x + 81) + 9

Therefore, the values sought are:

b = 1

c = 81

d = 9

Answer:

f (x) ^ - 1 = + / - root (x + 81) + 9

b = 1

c = 81

d = 9
