If f(x)=9x, which of the following is the inverse of f(x) a) f^-1(x)=9/x b) f^-1(x)=x-9 c) f^-1(x)=x+9 d) f^-1(x)=x/9 !

Step-by-step explanation:

Given :

To Find: Inverse of f(x)

Solution:

Replace x with y and y with x.

Thus the inverse is

Hence the inverse of is  

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3
