1. The problem asks to compare the graph of the second function $$y=\frac{1}{7}4^{-2x-10}-3$$ to the graph of the first function $$y=4^x$$.
2. Start with the first function $$y=4^x$$, which is an exponential growth function. It increases rapidly as $$x$$ increases.
3. Analyze the second function step-by-step:
- The base is still 4, but the exponent is $$-2x-10$$ instead of $$x$$.
- The negative sign in front of $$2x$$ reflects the graph across the y-axis.
- The factor 2 compresses the graph horizontally by a factor of $$\frac{1}{2}$$.
- The $$-10$$ inside the exponent shifts the graph horizontally to the right by 10 units (because $$-2x-10 = -2(x+5)$$).
- The coefficient $$\frac{1}{7}$$ vertically compresses the graph by a factor of $$\frac{1}{7}$$.
- The $$-3$$ outside shifts the graph downward by 3 units.
4. Summarizing the transformations from $$y=4^x$$ to $$y=\frac{1}{7}4^{-2x-10}-3$$:
- Reflection about the y-axis.
- Horizontal compression by factor 2.
- Horizontal shift right by 5 units.
- Vertical compression by factor $$\frac{1}{7}$$.
- Vertical shift downward by 3 units.
5. These transformations change the shape and position of the graph significantly compared to the original exponential growth curve.
Final answer: The second function's graph is a reflected, horizontally compressed, right-shifted, vertically compressed, and downward-shifted version of the first function's graph.
