[Show Answer]

Write Here

\left | 9y-6 \right |=3, then \left | y^2-\frac{4y}{3} \right |=?
Firstly we will find out the value of the y.
\left | 9y-6 \right |=3
\left | y^2-\frac{4y}{3} \right |
At y=1
\left | y^2-\frac{4y}{3} \right |=-1
At y=\frac{1}{3}
\left | y^2-\frac{4y}{3} \right |=\frac{-11}{27}=-0.4

i.e. the value of the function lie between -0.4 and -0.1, it is \frac{-1}{3} (Ans)
