Final answer:
The question is about a continuous random variable with a pdf of 4x³. You can evaluate the integral, solve for x, differentiate the function, or find the mean.
Step-by-step explanation:
The question is asking about a continuous random variable with a probability density function (pdf) of 4x³.
To evaluate the integral, we integrate 4x³ with respect to x over a given interval.
To solve for x, we need more information or a specific equation involving x.
To differentiate the function, we take the derivative of 4x³ with respect to x.
To find the mean, we calculate the expected value of x using the pdf.
