Question
Decide whether the functions defined as follows are probability density functions on the indicated intervals. If not, tell why.$$f(x)=10 x^{4} ;[0,2]$$
Step 1
The function $f(x)=10x^{4}$ is non-negative for all $x$ in $[0,2]$. So, the first condition for $f(x)$ to be a probability density function is satisfied. Show more…
