If f(x) = (x + 9 and g(x) = -6, which describes the value of (f + g)(x)?
(f + g)(x) > 3 for all values of x
(f + g)(x) < 3 for all values of x
(f + g)(x) = 6 for all values of x
(f + g)(x) > 6 for all values of x

Answer 1

نعم نعم نعم
(f+g)(x) is just the sum of the f and g functions.
it is x+3
so when x is 0 the output is 3, and as x rises the output also rises. For all positive values of x, it is greater than 3. So the answer should be A.
It doesn't seem to care about negative numbers though.
