if $f(x)=3lfloor x - 2\rfloor$, what is $f(5.9)$?\n9\n10\n11\n12

Explanation:

Step1: Substitute x value

Substitute $x = 5.9$ into $f(x)=3\lfloor x - 2\rfloor$. We get $f(5.9)=3\lfloor5.9 - 2\rfloor$.

Step2: Calculate the value inside the floor - function

First, calculate $5.9−2 = 3.9$. So, $f(5.9)=3\lfloor3.9\rfloor$.

Step3: Evaluate the floor - function

The floor of $3.9$, $\lfloor3.9\rfloor = 3$.

Step4: Calculate the final result

Then, $f(5.9)=3\times3=9$.
