G(x)=-3x+2 with domain of -1,2

Question

Help me plz ibneed help help  g(x)=-3x+2 with domain of -1,2 plz plz plz. 

 

Answer 1

G(x) = -3x + 2

 

The domain of G(x) is all real numbers.  But if you are given the restriction that x can only be -1 or 2, then G(x) can only be G(-1) or G(2).

 

G(-1) = -3(-1) + 2 = 5

G(2) = -3(2) + 2 = -4

 

I have to say this is a strange question.
