Answer:

Step-by-step explanation:
Hello
Step1
Let f(x)=y
f(x) = 2x + 1
(1)y= 2x + 1
to find the inverse of f(x)
Replace every x with a y and replace every y with an x
y= 2x + 1
replacing
x=2y+1
Step 2
Now solve the equation for y
x=2y+1
subtract 1 on both sides
x-1=2y+1-1
x-1=2y
divide boths dies by 2
(x-1)/2=2y/y

let this last equation h(x)= inverse of f(x)

Have a great day
h(x) = (x-1 ) /2 ...........

The answer is 141.7
If you add 60
X will equal 12, and y will equal 18.
