No . they are not equivalent

solution

3.5/42 = 35/420 = 7/84 = 1/12

Describe how to find the average rate of change between x=3 and x=5 for the function f(x)= 3x^3+2
Anastasy [175]

Answer:

We'll use the traditional "slope" formula, evaluating

\frac{f(5) - f(3)}{5-3}

To find f(5), plug in x = 5 to f(x).

3(5)^3 + 2 = 377

Same thing for f(3)

3(3)^3 + 2 = 83

So

\frac{377-83}{5-3} = \frac{294}{2} = 147
