Step-by-step explanation:
The answer:
the full question is if f(x) = 3 [ x - 2 ] , what is f(5.9)?
9
10
11
<span>12
</span>first, [x - 2 ] is called the integer part of x-2,
generally, to compute f(c) where c is a real number, it is sufficient to substitute the value of x by c.
so <span>f(5.9) = 3 [ 5.9 - 2 ] = 3 [ 3.9 ]
as we know that </span>[ 3.9 ]=3
<span>
therefore
</span>3 [ 3.9 ]<span>= 3x3 =9
the answer is 9</span>
