Math Problem Statement
Consider the function f(x) = 7^x. Given a table with x-values that get closer to π ≈ 3.14159265359 and their corresponding f(x) values. Use the table to approximate 7^π correct to four decimal places.
Solution
The table provides values of the function for values approaching . We need to approximate to four decimal places, using the closest approximation of .
Let's look at the table:
- The value closest to is .
- The corresponding value of is .
Thus, the approximation of , correct to four decimal places, is:
