Answer:

  c = 5

Step-by-step explanation:

The graph of

  f(x) = 3x² -5x -7

is shifted 2 units to the right by the transformation ...

  g(x) = f(x -2)

  g(x) = 3(x -2)² -5(x -2) -7

  g(x) = 3(x² -4x +4) -5x +10 -7

  g(x) = 3x² -17x +15

When this is written as a monic polynomial, it is

  g(x) = x² -17/3x +5

The value of 'c' is 5.
