Math help, please!

Hey, I'm good with chemistry. But there were problems with mathematics. Please help me I can't find the solution:

An important factor in solid missile fuel is the particle size distribution. Significant problems occur if the particle sizes are too large. From production data in the past, it has been determined that the particle size (in micrometers) distribution is characterized by f(x)=3x−4,for x>1,f(x)=0f(x)=3x−4,for x>1,f(x)=0, elsewhere.
a) Verify that this is a valid density function.
b) Evalute F(x).
c) What is the probability that a random particle from the manufactured fuel exceeds 4 micrometers?

I had a course in math, but to be honest, it's one of the most complicated subjects. Usually, when I need some help, my groupmate helps me because he is very good at math. But also, from time to time, I use this source where I always get help pretty fast. You can ask the math question you have, and you'll for sure get help there.
