Question

Consider the following graph.Step 1 of 2: Does the graph represent a function?AnswerKeybO YesΟ Νο

Answer 1

Step-by-step explanation

Step 1

to check if the graph is a function inspect the graph to see if any vertical line drawn would intersect the curve more than once. If there is any such line, the graph does not represent a function. If no vertical line can intersect the curve more than once, the graph does represent a function.

so

we can see that the function is intersect one time, so we can conclude

Yes, the graph is a function

Step 2

The domain is all x-values or inputs of a function and the range is all y-values or outputs of a function

A)Domain:When looking at a graph, the domain is all the values of the graph from left to right

the graph goes from negative infinite to positive infinite,so we can conclude

`\text{Domain. (-}\infty,\infty)`

B) Range:The range is all the values of the graph from down to up( Y -values)

therefore, the range is

`\text{Range: (-}\infty,-2)`

I hope this helps you
