a. all real numbers
b. y<= -5
c. y >= -5
d y>= -6

Answer 1

The range here is all of the y-values.

As you can see, the line stops at -4 going down, but going up, it goes on forever.

So the range would be from -4 and up.

We can write that in interval notation like this:
\[[-4,\infty)\]

Where '[' means inclusive and ')' means non-inclusive.

Answer 2

i think range is \[[-5,\infty )\]

Answer 3

or
\[y \geq -5\]

Answer 4

it starts from -5 and goes indefinitely up

Answer 5

I agree. [-5, infinity)
