Which of the following is true of a graph that passes both the vertical and horizontal line test? (Select all that apply.) Note: Make sure you select all of the correct options there may be more than one! Over the domain depicted, the graph represents a function Over the domain depicted, if the graph represents a function, then that function is invertible The graph is strictly increasing or decreasing: if \( x_{-} 1f\left(x_{-} 2\right) \) for any choice of \( x_{-} 1 \) and \( x_{-} 2 \) or \( x_{-} 1>x_{-} 2 \) then \( f\left(x_{-} 1\right)>f\left(x_{-} 2\right) \) for any choice of \( x_{-} 1 \) and \( x_{-} 2 \) If the graph represents a function, then that function never attains the same value twice over the domain depicted QUESTION 7 A food truck selling sandwiches rents parking spots from the city for \( \$ 500 \) per week. It spends a further \( \$ 200 \) per week on gas an maintenance. Each sandwich made costs the food truck \( \$ 2.50 \) and retails for \( \$ 6.00 \). Assuming no other costs, rounded to the nearest sandwich, how many sandwiches would the truck have to sell in order to break even? QUESTION 8 A laundromat buys a bank of 10 washing machines for \( \$ 500 \) each. They re assumed to depreciate in value to \( \$ 100 \) over the course of 10 years at a constant rate. To the nearest dollar, how much will they be worth after 6 years? QUESTION 9 A factory pays \( \mathrm{x} \) in monthly fixed costs and \( \$ 40.23 \) per unit manufactured. If, in a month where it produces 1,750 units, it pays a total of \( \$ 90,000 \) in fixed and variable costs combined, what is \( x \) ? Round to the nearest dollar.
