Answer:
f(x)=104x-x^2
Step-by-step explanation:
Let
x = number of tickets sold.
example, 2 tickets cost 2 · 408 = $816
3 tickets cost 3 · 404 = $738.
The cost of buying x tickets= the number of tickets sold × the price of each ticket.
If x tickets are sold, then the price of each ticket is 412-4(x-1)
Then the quadratic function that gives the total cost of buying x tickets is given by
Cost =quantity sold*price
=412-4(x-1)*x
=(412-4x+4)*x
=412x-4x^2+4x
=416x-4x^2
Divide through by 4
=104x-x^2
Therefore, the required quadratic function is
f(x)=104x-x^2
It’s operations Srry if I get it wrong

Answer:
Opt. B
Step-by-step explanation:
The key feature is to eval x in a point where |x| is zero, since the vertex of the function is located at that point.
|x|=0 means that y=-4.
Hence the vertex of this point is located at (0,-4)
4 Units down if we compare with the parent function y=|x|
