# Answer:
Here is a random AP Precalculus - aligned average rate of change problem: Consider the function $ f(x)=e^{0.5x}+2x^{2} $. Find the average rate of change of $ f(x) $ over the interval $[1, 4]$. Round your final answer to the nearest thousandth.

# Answer:
To find the average rate of change of a function $ y = f(x) $ over the interval $[a,b]$, we use the formula $ \text{Average Rate of Change}=\frac{f(b)-f(a)}{b - a} $

## Step 1: Find $ f(4) $
Given $ f(x)=e^{0.5x}+2x^{2} $, when $ x = 4 $:
$ f(4)=e^{0.5\times4}+2\times4^{2}=e^{2}+2\times16=e^{2} + 32$
We know that $ e^{2}\approx7.389 $, so $ f(4)\approx7.389+32 = 39.389 $

## Step 2: Find $ f(1) $
When $ x = 1 $:
$ f(1)=e^{0.5\times1}+2\times1^{2}=e^{0.5}+2$
We know that $ e^{0.5}\approx1.649 $, so $ f(1)\approx1.649 + 2=3.649 $

## Step 3: Calculate the average rate of change
Using the formula $ \frac{f(4)-f(1)}{4 - 1}=\frac{39.389-3.649}{3}=\frac{35.74}{3}\approx11.913 $

### 3)
a) # Answer:
(This would depend on the actual solution from ChatGPT. If we assume our calculation is correct) Yes.

b) # Brief Explanations:
(If the answer was incorrect) For example, if we made a mistake in calculating $ f(4) $ or $ f(1) $, the error could be in the calculation of the exponential term or the power term. To avoid such mistakes in the future, we should double - check the substitution of values into the function, use more precise values of exponential functions (e.g., using a calculator with more decimal places for $ e^{x} $ calculations), and re - verify the arithmetic operations involved in finding $ f(b) $, $ f(a) $ and the final division.
