I have my correct answers in the photo so just read from that :) <3
f(x) = sqrt [( x - 3) / (x - 5)]
well x cannot be 5 because that would make x - 5 = 0.
Also the fraction x - 3 / x - 5 cannot be negative because theres no real square root of a negative.
So x must be <= 3 or > 5
In interval notation the domain is ( -∞,3] or (5 , ∞)

Answer:
The profit equation would be: Profit = 10t - 425. To break even, 43 tickets must be sold, rounded up to the nearest whole number.
Step-by-step explanation:
Tickets = 10 * t, or $10 dollars per ticket
Prize = $425
Profit = (10 * t) - 425
Break-even is when the Function value would be Zero. This can be found by dividing the dollar amount by 10 to get 42.5 tickets or 43 tickets. After 43 tickets sold, the rest is profit.
The equation would be:
Profit = 10t - 425
A negative value would represent a net loss.
