Question

What is the range of the function graphed below?
1 -3 -2 -3

Answer 1

1-(-3)=4

Explanation:

To find the range you have to look at the list of numbers:

1, -2, -3, -3

Then you take the highest number, 1, and the lowest, -3, and then subtract.

1-(-3)

And once you do the math, that'll leave you with 4.
