Answer:
it means you are my neighbor
Step-by-step explanation:
=> y = (2x + 1) / (x - 4)
<span>=> xy - 4y = 2x + 1 </span>
<span>=> xy - 2x = 4y + 1 </span>
<span>=> x(y - 2) = 4y + 1 </span>
<span>=> x = (4y + 1) / (y - 2) </span>
<span>=> f-1(x) = (4x + 1) / (x - 2) </span>
<span>subtitute x = 3 </span>
<span>=> f-1(3) = 13</span>
