Answer:
y = lnx/ln12
Step-by-step explanation:
Given the function y = 12^x, to find the inverse of the function, we news to write x as a function of y as shown:
Given y = 12^x
Taking ln of both sides
ln y = ln 12^x
ln y = xln12
Divide both sides by ln12
lny/ln12 = xln12/ln12
x = lny/ln12
x = ln(y-12)
Replacing y with x and x with y
The inverse of the function will be:
y = lnx/ln12

Step-by-step explanation:
Okay mommy I just wanna cry lol yeah lol lol oh okay okay baby I promise promise I love mama mommy
Isolate x
So xy - 2 = k
Then
xy = k + 2
x = (k+2)/y
Answer:
x=-6
x=-4
