( f - g )(x) = 10x - 17 and ( f ° g)(-6) = 60. The answers are option D and B
<h3>There are different type of Function</h3>Different types of function demands different ways of solving them. Different types are simple function, function by substitution and function of function.
Given that
f(x) = + 9x - 14 and g(x) =
- x + 3
( f - g )(x) will be the difference between f(x) and g(x)
( f - g )(x) = + 9x - 14 - (
- x + 3)
( f - g )(x) = + 9x - 14 -
+ x - 3
( f - g )(x) = 10x - 17
Also, if f(x) = - 15 and g(x) = 1 - 2/3 x
( f ° g)(-6) means that we will evaluate g at -6, then evaluate f at the result of g(-6)
g(-6) = 1 - 2/3 (-6)
g(-6) = 1 + 4
g(-6) = 5
f(g(-6)) = 3() - 15
f(g(-6)) = 3 x 25 - 15
f(g(-6)) = 75 - 15
f(g(-6)) = 60
Therefore, ( f - g )(x) = 10x - 17 and ( f ° g)(-6) = 60
