Answer:
Place a dot on the x-axis at x = 0. Place a dot on the x-axis at x = 2. Place a dot on the x-axis at x = 7/2 which is the same as 3 1/2.
Explanation:
p(x) = 3x(x - 2)(2x - 7)
3x(x - 2)(2x - 7) = 0
x = 0 or x - 2 = 0 or 2x - 7 = 0
x = 0 or x = 2 or x = 7/2
Place a point on the x-axis at x = 0. Place a point on the x-axis at x = 2. Place a point on the x-axis at x = 7/2 which is the same as 3 1/2.
