    Real life expressions

    We encounter rational expressions all the time in the real world, often without even realizing it. Now it's your turn to come up with a real-world example from your work or personal life of using an equation with a rational expression to solve a real-world problem. Please give the example, setup the problem, th

    Injective, surjective, and bijective compositions.

    Let f: X--->Y and g: Y--->Z be functions. i. If both f and g are injective prove that g o f is injective. ii. If both f and g are surjective prove that g o f is surjective iii. If both f and g are bijective prove that g o f is bijective iv. If g o f is bijection, prove that f is an injection and g is a surjection.
