1. Problem Description
The problem provides a table of values for a function and asks to estimate the value of when . The table contains the following points: , , and .
2. Solution Steps
Since we are given three points, we can estimate the function value at using linear interpolation between the two closest points. The value lies between and . However, since is closer to , we will use the points and to find the equation of the line and interpolate.
The slope of the line passing through points and is:
Using the point-slope form of a line , we can write the equation of the line using the point :
Now, we substitute into the equation to estimate :
