Answer

\( f(x) = 8^{x-3} \) will eventually exceed \( g(x) = 10x \) as \( x \) becomes larger.

As \( x \) grows, the rate of growth of the exponential function \( f(x) = 8^{x-3} \) will eventually outstrip the linear function \( g(x) = 10x \). This is a fundamental principle in mathematics, where exponential functions increase much faster than linear functions as their inputs grow large. A common mistake when comparing these functions is underestimating how quickly exponentials accelerate compared to linear growth. While it may seem that \( g(x) \) could catch up at smaller values of \( x \), the sheer power of \( 8^{x-3} \) means that after a certain point (around \( x = 13 \)), it will dominate \( g(x) \). So, keep an eye on those exponents!
