A quadratic function f(x)f(x) is hidden from view. You must find the yy-intercept(s) of f(x)f(x) and write the answer(s) in the form (x, y)(x, y). Choose the form of the quadratic function f(x)f(x) that you would like to see in order to answer the question most efficiently.

Aparallel system functions whenever at least one of its components works. consider a parallel system of n components, and suppose each component works independently with probability 0.5. find the conditional probability that component n works given that the system is working
