Hi there!
• f(x) = 3x + 1
• g(x) = x² - 6
Then,
According to th' question :-
(f - g)(x) = f(x) - g(x)
= 3x + 1 - (x² - 6)
= 3x + 1 - x² + 6
= -x² + 3x + 7
Hence,
Option 2ⁿᵈ : -x² + 3x + 7 is Correct.
~ Hope it helps!

a) Equation:
b)
1st case: 119 tickets
2nd case: 106 tickets
3rd case: 95 tickets
Step-by-step explanation:
a)
Terry and Tony want to make a profit of
P = $475
in total from the ticket sale.
Here we call the price per ticket.
Then we also call the number of tickets sold: therefore, this total profit made by Terry and Tony from the ticket sale is the product between the tickets sold, N, and the price per ticket, x:
And since they want to do a profit of P = $475, we can therefore write
b)
The equation of part a) can be re-arranged as
where N is the number of tickets sold and x the price per ticket.
The 1st group of student want to charge $4.00 per ticket, so
x = 4.00
And so the number of tickets that they should sell in this case is
The 2nd group of student want to charge $4.50 per ticket, so
x = 4.50
And so the number of tickets that they should sell in this case is
Terry and Tony want to charge $5.00 per ticket, so
x = 5.00
And so the number of tickets that they should sell in this case is
