It is exponential.
Step-by-step explanation:
The x-values in the table are increasing by 9 and the y-values are multiplying by 2 each time. If the y value is increasing by addition, it will be linear, and if it increasing by multiplication it will be exponential.
Using a graphing website like desmos, or a graphing calculator, you can input these values to check if it is correct.
