<p>** I used the periods to space out the numbers**</p>

<p>x l f(x)
2... -1
3... 0
4... 2
5... -3
6... 4
7... -5
8... 6</p>

<p>Several values of the function f are shown above. The function of g is defined by g(x) = f(3x+1). What is the value of g(2)?</p>

<p>The choices are:
(a) -5
(b) -1
(c) 0
(d) 2
(e) 4</p>

<p>g(x) = f(3x+1)
g(2) = f(3*2 + 1) = f(7)</p>

<p>f(7) = -5 = g(2)</p>

<p>Wow… that looks so simple after you did it! haha</p>

<p>Thanks.</p>
