A friend looks at the graph of y = x and observes that if you start at the origin, the graph increases whether you go to the right or the left, so the graph is increasing everywhere. Explain why this reasoning is incorrect. Choose the correct answer below. O A. By the definition of an increasing function, a function is increasing if f (x1 ) > f (X2 ) whenever x, #X2. When the friend looks at the graph to the left of 0, this definition is broken. Thus, the function is not increasing everywhere. O B. By the definition of an increasing function, a function is increasing if f (X1 ) x2. When the friend looks at the graph to the left of 0, this definition is broken. Thus, the function is not increasing everywhere. O C. By the definition of an increasing function, a function is increasing if f (x1 ) > f (X2 ) whenever x,
