We are told that f(x) = x + 2. We want to find .
Squaring f(x) on one side means we square x + 2 on the other.
So,
f(x) = x + 2
(f(x))² = (x + 2)²
= (x + 2)(x + 2)
We can use FOIL to square x + 2. The first terms multiply to x², the outside terms to 2x, the inside terms to 2x and the last terms to 4.
= x² + 2x + 2x + 4
= x² + 4x + 4
So [f(x)]² = x² + 4x + 4
A: no
X = 3
2x + 3
2(3) + 3
6 + 3
9
For the other one:
2(x + 3)
2(3+3)
2(6)
12
2x + 3 and 2(x + 3) are not equivalent because one has parentheses, which means you will have to do parentheses first instead of multiplication (PEMDAS rule)
Hope this helps!

Step-by-step explanation:
Seeing its an arithmetic sequence
T1=1......T2=2.....T3=3
To get your constant difference
T2=T1 is also equals to T3=T2
so 3-2=1 and 2-1=1
therefore the constant difference is 1
The third option. Lmk if u need work
