Algebra

A f(0) = 0  (from the table )     g(0) = -(0-2)^2+3 = -1        So  A  is true  because 0 > -1

B  f(-6)    =   -120        g(-6) = - (-6-2)^2 + 3 = -61              So B is NOT true

C g(2) = -(2-2)^2+3 = 3     f(2) = -24                                   So C is true

D g(3) = -(3-2)^2+3 = 2     f(3) = -48(?)                                 So D is true too

I believe f(x)  = −6x^2

f(x)  for x = 0 .....  f(0)  = 0    g(0)  = −1    true

f(x)  for x =  − 6  .....  f(−6)  = −216     g(−6)  = −61    false

g(x) for x =  2  ....  f(2)  = −24    g(2) = 3   true

g(x) for x =  3  ....  f(3)  = −54    g(2) = 2    true
