Question

If f(x) = 1-x2 and g(x) = 1 - x which is the rule of function (f – g)(x)?

Answer 1

Answer:

-x^2 +x

Step-by-step explanation:

f(x) = 1-x^2

g(x) = 1 - x

f(x) - g(x) = 1-x^2  - (1 - x )

Distribute the minus sign

              = 1-x^2 -1 +x

Combine like terms

             = -x^2 +x
