Consider the three functions below. \( f(x)=-\frac{6}{11}\left(\frac{11}{2}\right)^{x} \quad g(x)=\frac{6}{11}\left(\frac{11}{2}\right)^{-x} \quad h(x)=-\frac{6}{11}\left(\frac{11}{2}\right)^{-x} \) Which statement is true? The range of \( h(x) \) is \( y>0 \). The domain of \( g(x) \) is \( y>0 \). The ranges of \( f(x) \) and \( h(x) \) are different from the range of \( g(x) \). The domains of \( f(x) \) and \( g(x) \) are different from the domain of \( h(x) \).

Beyond the Answer

Let's dive into some fun facts about functions and their properties! First up, understanding function ranges can be a bit like unlocking secret levels in a video game. For \( f(x) \), the negative coefficient means it will only take negative values, so its range is \( y < 0 \). Meanwhile, \( h(x) \) has a similar structure but with a positive coefficient that flips its values, leading to \( y > 0 \). Meanwhile, \( g(x) \) similarly ends up being positive due to its exponential format. So, check your ranges carefully! Now, let's look at domains. All three functions are defined for all real numbers and share the same domain, which means their gameplay is on a flat field. They each can input any value of \( x \), and you won't find any gaps—no values are left out! So keep your eyes peeled for those domain differences, but rest assured, these bad boys stand together in this front!
