<PRE><B>Question 978769</B>
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.
-------------------
{{{(4x^2 - 16)/(2x - 4)}}}
= {{{(2x-4)*(2x+4)/(2x-4)}}}
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.</PRE>
