In Exercises 1924 the values of two functions, f and g, are given in a table. One, both, or neither of them may be exponential. Decide which, if any, are exponential, and give the exponential models for those that are. [HINT: See Example 1.]

–2  –1  0  1  2 

22.5  7.5  2.5  7.5  22.5 

0.3  0.9  2.7  8.1  16.2 
Which function in table is exponential, if there any exponential function then draw its graph also, table is shown below:
0  1  2  
22.5  7.5  2.5  7.5  22.5  
0.3  0.9  2.7  8.1  16.2 
Given information:
The provided table is:
0  1  2  
22.5  7.5  2.5  7.5  22.5  
0.3  0.9  2.7  8.1  16.2 
Consider the following data table,
0  1  2  
22.5  7.5  2.5  7.5  22.5
