Hi
IF this is what You meant (please use parenthesis when posting for clarity)
f(x)= {{{(x^3-5^3)/highlight((x-5))}}}  ||Domain is all real number except x=5

f(x)= {{{((x-5)(x^2 + 5x + 25))/((x-5))= x^2 + 5x + 25 }}}
 f(x) = x^2 + 5x + 25
f(x) = (x+5/2)^2 - 25/4 + 100/4
f(x) = (x+ 5/2)^2 + 75/4   Parabola opening Upward V(-5/2,75/4)
Range is y &#8805; 75/4
