Question

Graph the given function using the given values of x. Also use the graph to determine the domain and range of the function.

g(x)=(square root of x+1)+2 ; x = -1, 0, 3, 8

Answer 1

Graph the given function using the given values of $x$ . Also use the graph to determine the domain and range of the function.

$\mathbf{g}(\mathbf{x}) = (\mathrm{square~root~of~x + 1}) + 2;\mathbf{x} = -1,0,3,8$

$g(x) = \sqrt{x + 1}$

the domain is $[-1, \infty)$

the range $[0,\infty)$
