# Math Help - functions

1. ## functions

Given g(x) = Squareroot(x-1) find
a)The domain of g;
b)the range of g
(inequalities like x> 2 should be typed as x>=2 etc..)

2. if $g(x)=\sqrt{x-1}$ then the domain of g(x) is whenever $x-1\geq 0$ which implies that the domain is $x \geq 1$.

Similarly, for the range we know that $g(x) \geq 0 \quad \forall{x}$
