Let f(x)=x^2 - 1 and g(x)=1 - 2x. Find the indicated values.

1. g(1/f(3))

2. f(x + h) - f(x) all over h

1)

Calculate the value of f(3)=3²-1 and substitute as the value of x in the expression of g(x).

2) Algebraically replace all occurrences of x in f(x) by (x+h) and evaluate f(x+h).
Subtract f(x) from f(x+h) and divide result by h.
