If f(x) = -x-2, what is /(x)?

Of (x) = 9x + 18
orf(x) 5x+2
Of(x) = 9x + 2
O x(x) = –2x+
+

If f(x) = -x-2, what is /(x)? Of (x) = 9x + 18 orf(x) 5x+2 Of(x) = 9x + 2 O x(x) = –2x-example-1

Answer:

(a)

Explanation:

To find the inverse function, solve ...

x = f(y)

__


x = f(y)\\\\x=(1)/(9)y-2\\\\x+2=(1)/(9)y\\\\9(x+2)=y\\\\y=9x+18\\\\\boxed{f^(-1)(x)=9x+18}

If f(x) = -x-2, what is /(x)? Of (x) = 9x + 18 orf(x) 5x+2 Of(x) = 9x + 2 O x(x) = –2x-example-1
