Question

What is the range of the following function?

Answer 1

Need to put it here first...

Answer 2

And done.

Answer 3

The range of a function is all the y values it can take; compare to the domain of a function which is all the x values it can take.
So, looking at the domain, we can see that the line only exists for values of x that are greater than or equal to -2; before then, at x = -3 for example, the line doesn't exist at all.
So from that, we can see that the domain of the function is
x≥−2


Using a similar mindset but using y, what would the range be?

Answer 4

@Nnesha ?

Answer 5

your range just means ALL the possible y-values that you can have for a function.
So looking at your graph...
What is the lowest y-value you can have ?

Answer 6

One?

Answer 7

That's correct! :D
Now we know the lowest possible y-value = 1.
I'm going to assume that your function is a continuous line so the y-value keeeeeeps on increasing and getting higher and higher and higher.

So basically y≥1 because this means y can EQUAL to 1 and is greater than 1 which is true for this function right? :))

Answer 8

Yes, I believe so.

Answer 9

yepp
