Answer
Explanation:
Step1: Analyze the exponential function
The exponential function $y = (\frac{3}{4})^x$ has the property that for all real - valued $x$, $(\frac{3}{4})^x>0$. This is because the base $\frac{3}{4}\in(0,1)$ and any non - zero number raised to a real power $x$ is positive.
Step2: Find the range of $f(x)$
Let $y = f(x)=(\frac{3}{4})^x - 4$. Since $(\frac{3}{4})^x>0$, then $y=(\frac{3}{4})^x - 4>0 - 4$. So $y>-4$.
Answer:
${y|y > - 4}$
