Which of the following is the graph of y=- square root x+1
maks197457 [2]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

y=-\sqrt{x+1}

Find the intercepts

<u>The y-intercept</u> is the value of y when the value of x is equal to zero

so

For x=0 -----> y=-\sqrt{0+1}=-1

The y-intercept is the point (0,-1)

<u>The x-intercept </u>is the value of x when the value of y is equal to zero

so

For y=0 -----> 0=-\sqrt{x+1} ----->x=-1

The x-intercept is the point (-1,0)

<em>Find the domain</em>

we know that

The radicand must be positive

so

x+1\geq0

x\geq-1

All real numbers greater than or equal to -1

The range is all real numbers less than or equal to -1

using a graphing tool

see the attached figure

Order least to greatest: -5, -8, 2, 0, 3, 1, -1
UkoKoshka [18]

-Least to greatest-

<h2>-8   -5   -1   0   1   2   3</h2>

The numbers that have a negative sign in front of them come first because they are less than 0. The other numbers can be ordered by what comes first. For example, 3 is bigger than 1 so 3 would come after 1.
