Given the functions
[tex]\begin{gathered} f(x)=2x-10 \\ g(x)=2x^2+12x+18 \\ h(x)=2x^3-8x^2-10x \end{gathered}[/tex]
The graph of the given functions
From the graph of the functions above, it can be seen that each of the functions have the same domain
[tex]-\infty
Thus, the domain is the same for each function.The answer is the first option.
