Evaluate (if possible) the function at the given variable(s) of the independent varible. Simplify the results?

Question

1. G(x)=3-x^2

a) g(0)

b) g(sqrt(3))

c) g(-2)

d) g(t-1)

2.F(x)= X^3

F(x+deltax)-F(x)/deltax

Answer 1

Alright, I don't have the whole answer, but I have parts of it (hope it helps):

a) g(0)=3-(0^2)

         =3-0

    g(0)=3

b) (this is one I can't help you on--sorry!)

c) g(-2)=3-(-2^2)

          =3-(-2*-2)

          =3-4

    g(-2)=-1

d) g(t-1)=3-(t-1)^2     the 2 can be distribute to t^2 and -1^2 (which is 1)

           =3-t^2+1

           =(3+1) - t^2

           =4-t^2

I know this doesn't answer the entire question, but I hope it helps!
