1. if f(x)=1-x^2 and g(x)=1-x which is the rule of function (f-g)(x)
a. 1+x
b. -x^2+x
c. -x^2-x+2
d. x^3-x^2-x+1

2. for the pair of functions, f and g, find (f•g)(x) and (g•f)(x).
f(x) = 3+x, g(x) = x^2 + 1

QUESTION 1

If f(x)=1-x² and g(x)=1-x,

Then,

(f-g)(x)=f(x)-g(x)

This implies that,

We simplify to get,

The correct choice is B.
