Answer: 3x+2/3
Step-by-step explanation: Given that f(x)=x-1/3 and g(x)=3x+1
(fog)(x) is the composition of the functions f and g.
(fog)(x)=f(g(x))
=f(3x+1) (In the function f(x) where there is x we substitute the x by
3x+1) so that
(fog)(x) =3x+1-1/3
=3x+2/3
It’s 2 using the rule -b/2a —> 8/4=2
Answer:
B. y = (x + 3)^2 - 17
Step-by-step explanation:
When Andy completes the square, he adds and subtracts the square of half the x-coefficient. That is, he adds and subtracts (6/2)² = 9:
... y = x² +6x +9 -8 -9
... y = (x² +6x +9) -17
... y = (x +3)² -17 . . . . . . . . matches selection B
Answer: (14/2)-5=2
Step-by-step explanation:
Answer:
n=9
Step-by-step explanation:
You isolate the variable, so subtract 18. Then you divide both sides by -1/2, and you get n.
