Can you please tell me what graph represents the function of f(x) = the quantity of 4 x squared minus 16, all over 2 x minus 4.
-------------------
%284x%5E2+-+16%29%2F%282x+-+4%29
= %282x-4%29%2A%282x%2B4%29%2F%282x-4%29
f(x) = 2x+4
--------------
The graph is a straight line.
Pick 2 values for x and find y.
Plot the 2 points and draw a straight line them.
-----------------
The only complication is that x = 2 makes the DEN of f(x) = 0, so that point (2,8) does not exist on the graph.
---
Draw the line and then mark that point as a hole in the function.
