state the domain for the following?
1.f(x)= square root (x-8)
x-8 must not be negative
Domain: all Real numbers >= 8
------------------------------
2.h(x)=3x^3+5x-3
Domain: all Real Numbers
------------------------------
3.m(x)=5/x^2+9
Domain: all Real Numbers
------------------------------
4.l(x)=5x-4
Domain: all Real Numbers
--------------------------
5.g(x)=7x+4/x+4
Domain: all Real Numbers except x=-4
=====================================
Cheers,
