Answer:
Step-by-step explanation:
The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.
Interval Notation:
(−∞,∞)
Set-Builder Notation:
{x|x∈R}
{xlx∈R} means -We write x ∈ X if x is an element of the set X and x /∈ X if x is not an element of X. If the definition of a “set” as a “collection” seems circular, that's because it is. ... then P ⊂ N, and N ⊂ R. The empty set ∅ and the whole set X are subsets of any ... We assign the starting point x1 to a subset in the following way: (a) x1 ∈ XX if.
Answer:
7.
Step-by-step explanation:
Follow the order of operations.
We do the operation in the bracket first. So we are left with:
2 * (2) + 3
We multiply before we add, so:
4 + 3.
Finally, we add.

I hope this helps!
Hi! So I got :
-3 —>20
-2 —>13
-1 —>8
0 —>5
1 —>4
2 —>5
3 —>8
I’m sorry if any of these are wrong but In order to find the answers I used the “graphing quadratics” one (don’t know the name so sorry) but yeah first I found the axis of symmetry which was 1 and from there I built a chart and substituted. Again, I didn’t see some answer choices above in the image so sorry if there wrong, but yeah I hope this helped! (This is from algebra 1 by the way)
This is no mistake he is the one
