exponential functions

Find a formula for the exponential function passing through the points (−2,32) and (1,4)Thank you so much!

An engineering system consisting of n components is said to be a k-out-of-n system (k . . . n) if the system functions if and only if at least k of the n components function.

Assume that each component independently works with probability 1/2. Find the conditional probability that component 1 is working, given that the system works, when k = 2, n = 3.
