The function is not one-to-one as it fails the horizontal line test. For example, both $f(0)=8$ and $f(-1)=8$ but $0
eq -1$. Therefore, there exist distinct inputs with same output, and the function is not one-to-one.

Determine Whether the Function Is One-To-One f(x)=x8+8f ( x ) = x ^ { 8 } + 8f(x)=x8+8

Determine Whether the Function Is One-To-One $f ( x ) = x ^ { 8 } + 8$
