$f(x)=\frac{\sqrt[\phantom{2}]{x^2-49}}{17}+\frac{8-8*x}{x+17}-\frac{5}{(x-14{)}^4*x^3}$

Which $of$ the followings sets are contained $in$ the domain $off?$

Indicate all that apply.

You will probably find this easier $if$ you first determine the domain and draw $iton$ the number line.

Remember that a set $Ais$ contained $in$ a set $Bif$ every member $of$ A also lies $inB.$
