Hello,
f(x) = 1/9x + 2 ⇔ y = 1/9x + 2 ⇔ 1/9x = y - 2 ⇔ x = 9(y - 2)
x = 9y - 18
⇒ f⁻¹(x) = 9x - 18
Answer:
Relative minimum:
, Relative maximum: 
Step-by-step explanation:
First, we obtain the First and Second Derivatives of the polynomic function:
First Derivative
(1)
Second Derivative
(2)
Now, we proceed with the First Derivative Test on (1):


The critical point is
.
As the second derivative is a constant function, we know that critical point leads to a minimum by Second Derivative Test, since
.
Lastly, we find the remaining component associated with the critical point by direct evaluation of the function:


There are relative maxima.
