What's true about the table?

• The table is growing by equal factors over equal intervals therefore it is a linear function

• The table is growing by equal differences over equal intervals therefore it is an exponential function

• The table is growing by equal factors over equal intervals therefore it is an exponential function

• The table is growing by equal differences over equal intervals therefore it is a linear function
