Okay so, we switch out f(x) with y - I’m sure you know this and we get y=2+3x/x-2.
Now just interchange x and y -> x=2+3y/y-2, now multiply both sides with (y-2), we get (y-2)x=2+3y.
Multiply x with the brackets, getting xy-2x=2+3y. Move 3y to the left changing it’s sign, also for -2x to the right: xy-3y=2+2x.
Factor out y from (xy-3y) and get (3-x)y=2+2x - now divide both sides by (3-x) resulting in y=2+2x/3-x .

Answer:
Fail to reject H0 in all three cases
Step-by-step explanation:
Given that a certain pen has been designed so that true average writing lifetime under controlled conditions (involving the use of a writing machine) is at least 10 hr.
(Right tailed test at 1% sign level)
n = 19
a) t =-2.5 , df = 18
p = 0.01154
p >1% hence Fail to reject H0
b) t = −1.83
p = 0.041931
p >1% Fail to reject H0
c) t = 0.57
p = 0.287>1% Fail to reject H0
