MHB Can someone help me figure out what to mark off on this graph?

Can someone help me figure out what to mark off on this graph? I am a beginner in Algebra 2 domain and range functions.

what are your choices for statements that are true?

recommend watching this video if you don’t have a clue ...

 

[a723w6]

I picked these as my initial choices, but I don't know if they're right.

 

[skeeter]

how can the range be all y-values and y > -4 at the same time?

you also say there is no minimum y-value, yet you also say the minimum is -4. ?

watch the video.

 

[a723w6]

Now I have this.

 

[skeeter]

the minimum value of a function is the lowest y-value on the graph.

your choice for the range is still incorrect.

what is the graph’s y-intercept?

 

[a723w6]

I changed my answer. It looks like the graph's y-intercept is (0, -3).

 

[skeeter]

ok ...

what are the x-intercepts?

 

[a723w6]

The x - intercepts are (-3, 0) and (1, 0).

 

[skeeter]

ok

you really need more algebra 1 review of graphing before tackling algebra 2 topics

recommend you do some research, view videos, etc.

good luck

Wait, what exactly did I say wrong?

 

[a723w6]

I have this now.

nothing srong, I’m just concerned that you had to be led through a series of questions to make the correct choices

the y-intercept is (0,-3), not (-3,0) ... you stated it correctly in post #7, but you checked (-3,0) in post #12.

attention to detail, get my drift?

 

[a723w6]

So all of my answers were correct in post #7?

I am a little bit uncomfortable with saying "the domain is all x-values" when we are shown only a portion of the graph. We can assume that the graph continues in the same way way but we can't be certain just by looking at that graph. IF this graph shows the entire function THEN the domain is $-4.2\le x\le 2.2$.
