Consider a random variable X with support [0, ∞), pdf f, and CDF F. The function h defined as h(x) = f(x)/1 − F(x) for x > 0. The function h is called the failure rate or the hazard function of X. What is the failure rate if X is exponential with parameter λ?

Question

Consider a random variable X with support [0, ∞), pdf f, and CDF F. The function h defined
as
h(x) = f(x)/1 − F(x)
for x > 0. The function h is called the failure rate or the hazard function of X. What is the
failure rate if X is exponential with parameter λ?

Expression, rule, or law that gives the relationship between an independent variable and dependent variable. Some important types of functions are injective function, surjective function, polynomial function, and inverse function.
