Step-by-step explanation:
Given

Required
Determine the inverse function
Start by replacing f(x) with y

Swap the positions of y and x

Make y the subject: <em>Add 4 to both sides</em>


Make y the subject: <em>Divide through by 2</em>
<em></em>
<em></em>
<em></em>
<em></em>
<em></em>
Replace y with f-1(x)

Recall the binomial theorem.

Answer:
B
Step-by-step explanation:
x + y =6
x - y = 4
A. 3+3=6, but 3-3 doesn't equal 4
B. 5+1=6 and 5-1 equals 4
C. 6+0 equals 6 but 6-0 doesn't equal 4
D. 2+4 equals 6 but 2-4 doesn't equal 4
Yes because 26 is an even number
