Answer: 12
Step-by-step explanation:
We know that , the ceiling function y = [x] is also known as the least integer function that gives the smallest integer greater than or equal to x.
For example : For x= 1.5
y = [1.5] =2
For x= 3.64
y = ⌊3.64⌋=4
The given function :
Then, for x= 5.9 , we have
[since [3.9]=4 (least integer function)]
Therefore, the value of f(5.9) is 12

Step-by-step explanation:
Factorize means convert and expression into multiple factors.
You have to find to factor that multiplied equals the original equation. Firts of all you split the expression of square X into 3X an X, so you guarantee that when you multiply 3X by X, the result is 3X^2.
After doing that, you need to think in numbers that equals the middle term (8X) and the constant (5).
-1 and -5 guarantee you that the multiplication of them results into +5, so you start with those numbers. Then you have to find where to put them in order to find the -8X.
-5 x X = -5X
-1 x 3X = -3X
And adding those two expresion you find the -8X that you need!
Please try to solve it multiplying term by term and check the final equation.
