Answer:
Step-by-step explanation:
Linear functions are usually of the form f(x) = mx + b. When the coefficient of x is positive, the function is increasing (since as x gets larger, f(x) increases). When the coefficient of x is negative, the function is decreasing (since as x gets larger, f(x) decreases).
Exponential functions are usually of the form f(x) = . When b is greater than 1, the function is increasing (exponential growth). When b is between 0 and 1, (non-inclusive) the function decreases (exponential decay).
The function in this question has 3 raised to the power of x, and since 3 is greater than 1, this represents exponential growth.
The property that allow us to write
is called the associative property. It states exactly that, in any sum with more than two terms, you are free to substitute any pair of sum with their sum.
The quotient is 0.8. hope that helped
