The graph of f(x) = 2x3 – 19x2 + 57x – 54 is shown below. On a coordinate plane, a graph of a function is in quadrants 1 and 4. The function goes through the x-axis at (2, 0), (3, ), and (4.5, 0). How many roots of f(x) are rational numbers?

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363

correct answer:

b.(19,-2)
