Answer:

c = 5

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.
