MHB 5.5.2 average value of sqrt{x} [0,4]

Click For Summary
The average value of the function \( \sqrt{x} \) over the interval [0, 4] is calculated using the formula \( f_{ave} = \frac{1}{b-a} \int_a^b f(x) \, dx \). Substituting \( a = 0 \) and \( b = 4 \), the integral evaluates to \( \frac{1}{4} \left[ \frac{2}{3} x^{\frac{3}{2}} \right]^4_0 \), resulting in \( \frac{4}{3} \). The calculation appears correct, and the user is considering sharing this problem on LinkedIn for increased visibility. Suggestions for enhancing the post are welcomed, especially since it has garnered attention despite not being a math-focused platform. Overall, the average value of \( \sqrt{x} \) on the specified interval is confirmed as \( \frac{4}{3} \).

Find the average value of the function on the given interval. $\sqrt{x}\quad [0,4]$
average value $\boxed{f_{ave}=\dfrac{1}{b-a}\int_a^b f(x) \ dx}$
so with $a=0$ and $b=4$ thus
$\dfrac{1}{4-0}\displaystyle\int_0^4 \sqrt{x} \ dx
\implies =\dfrac{1}{4}\left[\dfrac{2}{3}x^{\dfrac{3}{2}}\right]^4_0
\implies = \dfrac{1}{4}\dfrac{16}{3}=\dfrac{4}{3}$

ok, I think this is correct, but possible typos
I want to poIst this problem on Linkedin this week so if there is any added tips
i will add it in... been getting lots of views on IN even tho it is not essentually a math forum
of I Suggest they come here

Yes, that is correct
