![### Average Value of f(x)
#### Question:
What is the average value of \( f(x) \) between \( x = 1 \) and \( x = 5 \) for \( f(x) = 2^x \)?
#### Options:
- ○ 32
- ○ 31
- ○ 10.82
- ○ 9.28
To solve this, you need to find the average value of the function over the interval \([1,5]\). The average value of a continuous function \( f(x) \) over the interval \([a,b]\) is given by:
\[
\text{Average value} = \frac{1}{b-a} \int_{a}^{b} f(x) \, dx
\]
In this case, \( a = 1 \), \( b = 5 \), and \( f(x) = 2^x \). Therefore, you would compute:
\[
\text{Average value} = \frac{1}{5-1} \int_{1}^{5} 2^x \, dx
\]
After evaluating the integral and simplifying, you'll obtain the average value.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F1a92b920-e019-446e-b580-35fb69c82c25%2Fc35d5b56-b648-422b-8103-cc0f798a7041%2Fl3dbhxy_processed.png&w=3840&q=75)
