F(3) occurs when x =3. So lets plug 3 into our equation.

$f(3) = -4(3)^2 + 4(3)-4\\f(3) = -4(9) + 12- 4\\f(3) = -36 + 12- 4\\f(3)= -28$

F(3) = -28

I hope this helps! :)

Answer:

After 15 days they'll both have $10

Explanation:

100 (Xavier's total)- 6x (6 dollars every day) = 160 (Zach's total amount) -10x (10 dollars every day)

$100-6x=160-10x\\$

+10x on both sides

$100+4x=160$

-100 on both sides

$4x=60$

/4 on both sides

$x=15$

5/6=0.83~
Meanwhile 3/4=0.75.
5/6 is bigger than 3/4.
Good luck!
