    f(x) = 2x + 1 f(0) = 2*0 + 1 = 1 f(3) = 2*3 +1 = 7

    6/3 and for the first one is f(6)/3? IDK is hard

    y = 2x + 1 is the equation of a line. A line has a constant rate of change. y = m*x + b where m is the slope (think rate of change) m = 2 which verifies what we already knew as the average rate of change.
