The range is all positive real numbers
Just substitute the x for each of the values and do the work
The factors are 3x, 4x^2-3 and 5x+2
So, Option B, C and F are correct.
Step-by-step explanation:
We need to find factors of the expression 
Solving the expression: 
Taking 3x common:

Now, factor by grouping, the terms inside the bracket.



So, the factors are 3x, 4x^2-3 and 5x+2
So, Option B, C and F are correct.
