Question

Someone please help me i don’t understand

Answer 1

Answer B

Explanation:

Write out f(x) and g(x) in a column; we will subtract g(x) from f(x):

f(x) = x^2 - 9 or f(x) = x^2 - 9

-g(x) = -(2 - x) or -g(x) = +x -2

---------------------------------

f(x) - g(x) = x^2 + x - 11 (Answer B)
