Answer:
y²-3y+2=0
=> y²-(2+1)y +2=0
=> y²-2y-y+2=0
=> y(y-2)-1(y-2)=0
=> (y-2)(y-1)=0
=> y = 2 or y= 1
so it would be f=36
Step-by-step explanation:
subtract 4 to the other side then multiply both sides by 3
Given function
To find an inverse for any given function, which is of the form , always swap and in the equation and try to get the form . Now, swapping back and , we get the inverse function.
On swapping and , we get
Swapping back and , we get
This is the inverse function.
