Answer:
D : All real numbers
R : (-∞,∞)
Step-by-step explanation:
When your x is in a set of absolute value sign, any number can work for x.
As with Domain, you can do the same with range. In this case, you can go from both positive infinity and negative infinity and you will always get a real number solution.
Answer:
6x^2 + 3x + 21 = 3(2x^2 + x + 7)
Step-by-step explanation:
We have this as follows;
6x^2 + 3x + 21 = 3(2x^2 + x + 7)
The quadratic trinomial inside the bracket cannot be factored any further
so we have the present form as the correct answer
Here are the laws of exponents:



Hope that helps :)
