Composite Function With Differing Bases?

**Biff** · September 4th 2012, 08:14 AM

Problem:

If $f(x)=\tan(x)$ and $g(x)=3_x 2$ , then $\left(g \circ f \right)\left(\frac{\pi}{6}\right) =$

1
$3 \left(\frac{\pi}{6}\right)^2$
$\tan \left(\left(\frac{\pi}{6}\right)^2\right)$
1.077
None of the Above

I realize that the composite function will look something like this:

$\left(g \circ f \right)\left(\frac{\pi}{6}\right) = 3_{\tan \left(\frac{\pi}{6}\right)} 2$

But the subscript $x$ throws me off; would someone please explain how that works?

Thanks in advance.

Oh, nevermind. It turns out that the math rendering obfuscated the meaning of $g(x)$ . Instead, it is: $g(x) = 3x^2$ .

The answer is 1.
