Question

For the data that are shown on the graph below, within which range of x values can interpolation occur?

- Between 1 and 10
- 0 and 55
- 5 and 55
- 25 and 50

Answer 1

D. 25-50

Explanation:

Answer 2

25-50

Explanation:

Since the graph shows us only values of x that are between 25 and 50, this is the correct answer.

We can interpolate with known data. However, once the interpolation occurs, and we approximate the data for a line of the form y = mx + b (m <0 , linear negative association), we could find the other values of y for a wider range of x values.
