Final answer:
For a function that shows exponential growth, an increase of 1 unit in the variable causes the function to be multiplied by the growth factor. The correct answer is true.
Step-by-step explanation:
The statement is true. For a function that shows exponential growth, an increase of 1 unit in the variable causes the function to be multiplied by the growth factor.
For example, if the growth factor is 2, every time the variable increases by 1 unit, the function value doubles. So, if the function is initially 4 and the variable increases by 1 unit, the new function value will be 8.
Therefore, the correct answer is a-true.
