Answer

The cumulative distribution function for the given continuous probability distribution is F(x)=x6124000+3x4124000+3x2124000999124000, defined on the domain [3,7].

Steps

Step 1 :Find the cumulative distribution function (CDF) by integrating the given probability density function (PDF) f(x) over the domain [3,x] where 3x7: F(x)=3xf(t)dt

Step 2 :The cumulative distribution function for the given continuous probability distribution is F(x)=x6124000+3x4124000+3x2124000999124000, defined on the domain [3,7].
