Given:

 f(x)=12\displaystyle {f{{\left({x}\right)}}}=-{12} 

State the domain of the function. Then identify the range, any intercepts, and any symmetry. If there are no intercepts please type 'none.'

(i) Domain =  

(ii) Range =

(iii) x-intercepts = 

(iv) y-intercept = 

(iv) f(x)\displaystyle {f{{\left({x}\right)}}} is  and has
