Question

Graph the function f(x) =
`√(x + 1 - 2)`Place cursor on the moveable point to adjust the graph.

Answer 1

we have

`f(x)=\sqrt[]{x+1}-2`

In this problem we know that the radicand must be greater than or equal to zero

so

`\begin{gathered} x+1\ge0 \\ x\ge-1 \end{gathered}`

the domain of the function is the interval for x {-1, infinite)

the range is the interval {-2, infinite)

using a graphing tool

see the attached figure

please wait a minute

this is the graph of the function
