Answer:
f^-1 = 4(x-3)
Step-by-step explanation:
If f(x) = 1/4(x) + 3 we ned to find f^-1.
To find the inverse function, we need to solve the equation for "x", as follows:
f(x) = 1/4(x) + 3
y = 1/4(x) + 3
y-3 = 1/4(x)
4(y-3) = x
Now, change the "x" for an "y". And change the "y" for an "x":
4(x-3) = y
The solution is the last one.
Answer:
Step-by-step explanation:
We can find the angle directly above the 
.
We know that because they both lie on a straight line, the other angle is 
.
Aha! We have a path to the solution!
because of the parallel line angle theorem(I forget what it's called).
We then add 
and 
to both sides to get 
.
Lastly, we divide by 
to get 
.
So, 
and we're done!
Do you have a picture of the problem to go with this because its not enough info to solve it
