Step-by-step explanation:
As we can see the question given
f(x) is varying accordingly to the interval
<em> f(x) = 2 if 2<x≤4</em>
The value of function is 2 for the interval 2 to 4
and interval is open at x=2 and closed at x = 4
<em> f(x) = x + 3 if 4<x<8</em>
The value of function is x + 3 and it is open at x = 4 and x = 8
<em>f(x) = 2x if x 8</em>
The value of function is 2x for x greater than or equal to 8
