Hi
we can write: f(x)= (x-2)^2
So for f(x+2), we replace x in f(x) by x+2
That means: f(x+2)= (x+2-2)^2=x^2.
Then the answer is x^2 and you are right.
Hope that you understand.

Answer:
Cards with Mark = 30
Cards with Drew = 120
Cards with Katie = 12
Step-by-step explanation:
The complete question is
Drew has 4 times as many baseball cards as Mark. Katie has 3 fewer than than half as many cards as Mark. In all they have 162 baseball cards. How many does each have?
Solution -
Let the number of cards with Mark be "X"
Number of cards with Drew = 4 *X = 4X
Number of Cards with Katies = 0.5 X -3
Sum of all the cards is equal to 162
X+4X + 0.5 X -3 = 162
5.5 X = 165
X = 30
Cards with Mark = 30
Cards with Drew = 4 * 30 = 120
Cards with Katei = 15-3 = 12
<span>Julia is X+5
</span><span>x+x+5=31
</span>
Now we just solve the equation
2x=31-5
x=26/2
x=13 years old (Babs' age)
and we know that julia is 5 years older this gives us the conclusion that.
13+18=31
