# Cpm homework answers algebra 2

### Question:

What are the domain and range?

### Answer:

Step 1

(a) Since neither mass nor radius can be negative, the function’s domain and range are [0,). Both can be true positive numbers that make sense or don’t make sense.

b) When there are a lot of data points, this equation is a good model.

The is large data set

Result

(a) [0,∞) (b) data set is large

The set of all values for which a function f(x) is defined is called its domain. The set of all the values that f can take is called its range. But most of the time, and especially when we’re working with graphs on the coordinate plane, we’re interested in functions where each part of the domain corresponds to a part of the range.
