The point P (4, 0) lies on the function of f(x) = 4x - x2. If Q is the point (x, 4x - x ) , graph the function f(x) and the secant lines PQ passing through P (4, 0) for each value of x below. Also find the slope for each value. Only a simplified fraction will be accepted. If a = 5, the slope of PQ is: If a = 4.5 , the slope of PQ is: If a = 3.5 , the slope of PQ is: Graph N w - 7 -6 -5 -4 -2 -1 2 3 4 5 6 7 8 9 10 11 4 -2 -3 in A
