1. (counting functions) let a be a set with m elements and b be a set with n elements in it. (a) what is the total number of functions from a to b? (b) what is the total number of one-to-one functions from a to b? verify your answer by considering the following cases m3, n4 . m=3, n=3 3, n =2 m (c) what is the total number of functions from b to a?

Can someone me out here and the tell me the greatest common factor

X+ y = 5 ; x - y =3 solve using linear combination

A. plot the data for the functions f(x) and g(x) on a grid and connect the points. x -2 -1 0 1 2 f(x) 1/9 1/3 1 3 9 x -2 -1 0 1 2 g(x) -4 -2 0 2 4 b. which function could be described as exponential and which as linear? explain. c. if the functions continue with the same pattern, will the function values ever be equal? if so, give estimates for the value of x that will make the function values equals. if not, explain why the function values will never be equal.
