To find the average rate of change of a function \( f(x) \) over the interval \([a, b]\), you can use the formula:
\[ \text{Average Rate of Change} = \frac{f(b) - f(a)}{b - a} \]
In your case, the interval is \([1, 4]\). Therefore, we only need the values of \( f(1) \) and \( f(4) \) to calculate the average rate of change.
However, you haven't provided the function \( f(x) \) or its values at those points. If you can provide those function values, I can help you calculate the average rate of change and find the correct response from the provided options.
