To find: The function is linear, exponential or neither.

Answer to Problem 26AYU
Solution:
Linear function.
Explanation of Solution
Given:
x | -1 | 0 | 1 | 2 | 3 |
f ( x ) | 2 | 5 | 8 | 11 | 14 |
From the above table, the average rate of change for every 1 unit increases in x is 3. Therefore the function is a linear function. In a linear function the average rate of change is the slope
