Write the algebraic expression that matches each graph:

An assembly consists of two mechanical components. suppose that the probabilities that the first and second components meet specifications are 0.87 and 0.84. assume that the components are independent. determine the probability mass function of the number of components in the assembly that meet specifications. x

Which graph corresponds to the function f(x) = x2 + 4x – 1?
