For this case we propose a rule of three:
page ----------> hour
x ---------------------------------> 1 hour
Where the variable x is the number of pages written in one hour.
Thus, Ophelia types 2 pages in 1 hour.

Step-by-step explanation:
The absolute value | | operator predicts that the graph will have a sharp corner around x=0. The minus sign tells you the legs of the graph will point in the negative y direction. The +3 tells you the graph is lifted +3 above the origin.
F(x) does not pass the horizontal line test, so its inverse is not a function.
Write it as y = f(x), then interchange variables and solve for y.
y = (1/9)(x - 4)²
x = (1/9)(y - 4)²
9x = (y - 4)²
±3√x = y - 4
y = 4 ± 3√x
f⁻¹(x) = 4 ± 3√x
